Installation Instructions Ambient Conditions Before you set up your balance, choose a suitable place which meets the following requirements: – level, low-vibration weighing table or a wall console; – no direct exposure to sunlight, heaters, or similar sources of heat.
Using Verified Balances Approved as Legal Measuring Instruments in Europe (only applies to MC5-0CE) Using Verified Balances as Legal Measuring Instruments You must calibrate the balance at the place of installation before using it as a legal measuring instrument (see the section entitled “Calibration/ Adjustment” starting on page 1–31). This balance is not allowed to be used for weighing goods intended for direct sale to the public.
Getting Started MC 210 S, MC 210 P and MC 410 S (-0CE): Important Note Concerning Verified Balances Approved for Use as Legal Measuring Instruments: Provided that an official lead seal is required for the verified balance, a control seal is affixed to the balance. Unauthorized attempts to remove this seal will irreversibly damage it. If you break the seal, the validity of the verification will become void, and you must have your balance subsequently verified.
Adjusting the Exterior Draft Shield Element Turn the exterior draft shield element (3) by the riffled part on the bottom to the position you desire. Depending on your application, you can define the menu code so that the interior draft shield door (4) is operated by motor or by hand (see section starting on page 1–21). Adjusting the Swivel-Mounted Display Unit Move the swivel-mounted display unit (11) around the base of the draft shield to adjust it to the position you desire (+/– 85°).
MC 5 (-0CE) and SC 2 (-0CE): Assembling the Components § Place the components listed below on the weighing cell (35) one at a time in the order given: – Protective disk (8) – Weighing pan (7) Important Note: After placing the weighing pan on the weighing cell, press down on it gently while turning it slightly to the left and right.
Connecting the Balance to AC Power The balance is energized by a power supply/AC adapter. Make sure that the voltage rating printed on this unit is identical to your local line voltage. If the voltage specified on the label or the plug design of the power supply/AC adapter does not match the rating or standard you use, please contact your Sartorius office or dealer. Important Note: Use only original Sartorius power supplies/AC adapters.
Voltage Selection 230 V~ 115 V~ You can select the voltage if you use our portable power supply (6971172) that has a European-type plug (rounded prongs). Safety Precautions The power supply/AC adapter rated to Class 2 can be plugged into a wall outlet without taking any additional safety precautions. The pole of the output voltage is connected to the balance housing, which can be grounded for operation.
Leveling the Weighing Cell Using the Level Indicator At the point of use, level the weighing cell using the leveling feet (9) so that the air bubble is centered within the circle of the level indicator (10). To level the weighing cell using the level indicator as a guide: Extend the leveling feet (turn clockwise) to lift the weighing cell. Retract the feet (turn counterclockwise) to lower the weighing cell.
General Instructions for “Analytical Weighing” Weighing Electrostatically Charged Samples and Containers Major measuring errors can occur when electrostatically charged samples and containers are weighed. This problem particularly involves samples that have an extremely poor electrical conductivity (glass, plastic, filters) since they can discharge electrostatic – i.e., friction-induced – charges only over a relatively long period of time.
Weighing Magnetic or Magnetizable Samples It is technically impossible to avoid the use of magnetizable materials in the manufacture of balances. Ultimately, the operating principle of high-resolution balances is based on electromagnetic force compensation of the load placed on the weighing pan. When magnetic or magnetizable samples or containers (e.g., beaker with a stirrer) are weighed, interactions among the above-mentioned components of the balance may occur, distorting weight readouts.
General Instructions for Handling Samples and Containers As a general rule, the sample to be weighed should be conditioned to the temperature of the balance. This is the only way to avoid air buoyancy errors and deviations caused by convection currents at the surface of the sample. Since these effects increase proportionally to the volume and surface of the sample, make sure that the size of the tare vessel selected is in the appropriate proportion to the size of the sample to be weighed.
Operating the Balance Balance Display The display shows the following special codes for your information: OFF The balance was disconnected from AC power (power failure or outage; the balance was reconnected to AC power). O (standby) The display has been turned off by the e key (31). The balance is now in the ready-to-operate mode. b (busy) Once you have turned on the balance, the b symbol will be displayed until you press a key.
Turning the Display On and Off (Standby Mode) Press the e key (31) to turn the display on or off. Self-Test After the balance has been turned on, an automatic self-test of the balance’s electronic circuitry is performed, and the draft shield closes automatically. When a zero readout is displayed, the balance is ready for operation. Important Note Concerning Verified Balances Approved for Use as Legal Measuring Instruments in the E.U.
Opening and Closing the Draft Shield MC 210 S, MC 210 P or MC 410 S (-0CE): To load small objects, open the draft shield only as far as is absolutely necessary for your application. This reduces the amount of draft so your balance will stabilize faster than it normally does when the draft shield is wide open. You have several options for operating the interior draft shield door (4): – Semi-automatically using the l or r key (23) (max.
Press either l or r to close the draft shield automatically by motor. While closing, the interior draft shield door moves slowly. The previously adjusted aperture angle is stored. If you press either l or r once again, the draft shield door will open at a faster speed to the position you have selected. Press l or r for approx. 2 seconds to open the draft shield door automatically as far as it will go (170°).
MC 5, SC 2 (-0CE): You can operate the motorized draft shield (34) in one of the following ways: – Semiautomatically using the l or r key (23) (aperature angle approx. 100°) – Using an external foot or hand switch (see part 5, “Accessories”) – By a command from an on-line computer (see part 4, “Interface Description”) – Fully automatically, e.g., for the functions tare, calibration, print, etc.
Semi-automatic Mode with the Aperture Angle of Your Choice To define the aperture angle and the direction in which the draft shield opens, move the draft shield to the desired position manually (aperture angle 45° to 315°). Press either the l or r key (23) to have the draft shield closed by motor. The previously adjusted aperture angle and the direction are stored in the process. You can always change the aperture angle by manually adjusting the position of the draft shield.
Numeric Entry of an Aperture Angle The numeric entry of an aperture angle corresponds to a fixed position. The aperture is measured counterclockwise starting from the closed draft shield position: – Enter an aperture angle between 45° and 315° using the numeric keys (20); e.g.
Simple Weighing Place your sample on the weighing pan (7), and close the draft shield door. Read off the weight indicated on the display (28) only after the weight unit (“g”, or a different unit selected – see part 2, “Balance Operating Menu”) appears as the stability symbol. Important Note Concerning Verified Balances of Accuracy Class k To avoid measuring errors, the respective air density must be allowed for.
Weighing Range Structure SuperRange “Single Wide-Range” (identified by S in the model name MC.....S) 210 g 0.01 mg SuperRange models have an extraordinarily high resolution; i.e., the weighing range has a resolution ranging from 100,000 to a few million digits. There is one level of fine readability for the entire weighing range (for example: 0.01 mg). PolyRange “Multi-Interval” (identified by P in the model name MC.....P) 210 g 110 g 60 g 0.05 mg - 0.00 mg - 0.02 mg 0.
Weighing in the IQ-Mode* (Load-Dependent Readability) In the IQ-mode, weighing is done with a loaddependent readability of, e.g., 0.01% (for different settings, see part 2, “Balance Operating Menu”) throughout the entire weighing range of the balance. Oftentimes, a display accuracy of 10 mg is sufficient for a load of approx. 110 g. In this case, it makes sense to select weighing range R 1 with an accuracy of 0.01% by pressing the w key (29).
Mass Unit Conversion by Toggling You can have the weight displayed in milligrams or grams. To select the weight units one after the other, press the w key (29) each time. In addition to milligrams and grams, the standard balances give you a wide variety of other menudefinable international weight unit options. For more information, refer to part 2, “Balance Operating Menu.
Calibration/Adjustment and Linearization Functions During calibration, the span* of your balance is adjusted to changes in ambient conditions. Relinearize your balance each time you set it up in a different area or recalibrate (re-adjust) it when the ambient conditions change (for example, temperature or barometric pressure). Even if these conditions are constant, the balance should be calibrated once a day.
The balance offers you various calibration and linearization functions. You can interrupt any calibration or linearization procedure by pressing the c key (32). In the fully automatic mode, the draft shield closes after the f or the t key has been pressed.
Internal Calibration Using the Tare Key: Calibrate the balance using the tare key if an application program (such as the tare memory) is assigned to the f key by menu code in the balance operating menu (see parts 2 and 3). Press the tare key (26) for at least 2 seconds until “C.I.” and “CAL” are displayed (next to the f key). Unload the pan and tare (if necessary, close the draft shield). When the balance displays a zero readout, press the f key (21). “C” will now be displayed.
For “external calibration,” press the F key (22) until “C.E.” is displayed. “C.E.” stands for “external calibration.” Unload the weighing pan (7) and tare (close the draft shield). Press the f key (21) when a zero readout is displayed. Afterwards, the calibration weight readout will be in grams. If external interference affects the calibration procedure, you may obtain a brief display of the error message “Err 02.” In this case, tare and then press the f key again when a zero readout appears.
Calibration Test The calibration test is carried out with internal weights as follows: – MC 210 S and MC 210 P (-0CE) with approx. 170 g – MC 410 S (-0CE) with approx. 300 g – MC 5 (-0CE) with approx. 5g – SC 2 (-0CE) with approx. 2g Press the tare key (26) for at least 2 seconds until “C.I.” and “CAL” are displayed (next to the f key). Select the calibration test by pressing the F key (22) twice until “C.t.” is displayed. Unload the balance and tare (close the draft shield). “C.t.
Internal Linearization Press the t key (26) for at least 2 seconds until “C.I.” and “CAL” are displayed (next to the f key). Select “internal linearization” by pressing the F key (22) several times until “L.I.” is displayed. Unload the balance and tare (close the draft shield). “L.1.” stands for “internal linearization.” When a zero readout is displayed, press the f key (21). “C” will now be indicated.
Data Interface If you wish to record weight data using a Sartorius Data Printer, plug the printer connector into the interface port (14) of the balance. You do not need to adjust any settings. Important Note for Verified Balances Approved for Use as Legal Measuring Instruments: When using the balance as a legal measuring instrument, you may connect to it only auxiliary devices that are legally permitted.
Below-Balance Weighing A port with a below-balance weighing hanger is available on the bottom of the balance. To hook a sample on the hanger, open the below-balance port by removing the two screws from the bottom of the balance and detaching the cover plate and gasket. Now you can attach a sample using a suspension wire, for example. You also have to install a shield to protect against drafts.

Care and Maintenance Servicing Regular servicing by a Sartorius service technician will extend the service life of your balance. Sartorius can offer you service contracts with your choice of regular maintenance intervals ranging from 1 month to 2 years. Cleaning the Balance Housing and the Draft Shield Before cleaning the balance, unplug the power supply from the wall outlet. Please do not use any aggressive cleaning agents (solvents or similar agents).
Safety Precautions If there is any indication that safe operation of the balance with the power supply/AC adapter is no longer warranted, turn off the power and unplug the equipment from AC power immediately. Lock the equipment in a secure place to ensure that it cannot be used for the time being.
Balance Operating Menu The Sartorius MC 1 Balance can be adjusted to meet your special requirements; e.g., to weigh in various units of measure, adapt to unfavorable conditions and process weight data for a variety of applications. In the operating menu, you can define how your balance will adapt to ambient conditions, and also how it will work to meet your needs. The factory-set menu codes are identified by an “*.” You can select the functions not identified by an “*” by setting the respective menu code.
Changing a Menu Code Setting To select specific functions, you will need to set the respective menu code. There are three steps to changing a code: – Accessing the menu – Setting a code – Confirming and storing this code For setting menu codes, the keys have special functions.
– Press the f key to change the left-hand number to “3” – Press p to move to the middle number – Now press the p key to move to the right-hand number (When you move to the right-hand number, the previously set numeric code will be indicated). – Press the f key to change the right-hand number to “4” Confirm the Code Setting – You must press the t key in order to confirm the code you have just set. This is indicated by the “o” after the code.
Please do not forget to relock the balance operating menu. The “-L-” indicates that it is currently locked: To use the locking function, make sure code 8 1 2 is set in the balance operating menu. If code 8 1 1 is set, the menu access switch will not lock.
Balance Operating Parameters Adapting the Balance to Ambient Conditions To adapt your balance to ambient conditions, you may need to change the response time (see the “Specifications”). Very stable conditions Stable conditions Unstable conditions Very unstable conditions Code 1 1 1 1 1 1 1 1 1 2* 3 4 Standard Weighing Mode – Manual Filling Mode You can optimally adapt your balance to meet either of these requirements.

Weighing in Two Ranges on Verified Balances Approved for Use as Legal Measuring Instruments The toggle key, w, lets you switch back and forth between two weighing ranges, provided you are using the factory-set menu code.
Display Modes for Standard Balances You can select the display mode that best meets your individual requirements. Last Numeral Blanked When the Load Changes As the load on your balance changes, the display resolution is reduced by a factor of 10 so that you will obtain a faster and more stable readout. Once the load has stabilized, the readout is shown again with the full display accuracy, which means the last numeral is displayed.
PolyRange Function (application for single-range balances) The PolyRange function divides a single weighing range into as many as 4 ranges, each with a different readability. In the various ranges, the readability will adjust so that the last numeral of a weight readout is displayed with a resolution of 1, 2, 5 or 10 digits (10 digits = only the next to the last numeral of the readout will change; the last numeral is blanked).
Display Modes for Verified Balances Approved for Use as Legal Measuring Instruments You can select the display mode that best meets your individual requirements. Last Numeral Blanked When the Load Changes As the load on your balance changes, the display resolution is reduced by a factor of 10 so that you will obtain a faster and more stable readout. In the process, the last numeral is blanked until the load stabilizes.
Calibration Functions on Standard Balances Select the appropriate menu code to define the access status for each of the calibration functions, which are activated by holding down the t key for a few seconds. If the menu access switch is unlocked (“accessible” status indicated by -C- after you have accessed the balance operating menu), the “external calibration” function will be accessible even though you have set the menu code 1 9 2 for “access denied.
Multiple Calibration Mode The calibration value is calculated from the average of the individual calibration procedures. You can use the “multiple calibration mode” for both internal and external calibration. The number of calibration procedures is indicated in the 3rd place of the application display field (e.g., “C.I.3”). Important Note: If “Err 04” is briefly displayed, the calibration values deviate too much from one another.
Calibration Functions on Verified Balances Approved for Use as Legal Measuring Instruments Select the appropriate menu code to define the access status for each of the following calibration functions, which are activated by holding down the t key for a few seconds: – External calibration – Internal calibration – Calibration – Internal linearization – Air density determination C.E.

Afterwards, you may use the balance only in the legally restricted temperature range from +15 °C to +25 °C.
Utilities for Printouts or Data Transfer The balance operating menu lets you define the various parameters for data output. For information on the data formats and for interfacing a computer or a different peripheral device, see part 4, “Interface Description.
Data Output at Defined Intervals You can reduce the volume of data in the “auto print” mode by defining the interval at which data will be output automatically. This auto print interval is based on the number of times the display is updated.
Data ID Codes To help you identify weights, piece counts, percentages, etc., a code letter is printed or displayed in front of these values. For example, an “N” printed or displayed before a weight value identifies it as a net weight. If you set the code for “without data ID code,” only net weights, results in percent, and counting results will be output. The ID code increases the data output format from 16 to 22 characters for each weight readout.
Additional Functions Menu Access Function You can define the function of the menu access switch by setting the code for the balance operating menu to “accessible.” In this setting, “-C-” will be displayed on your balance whenever you access the menu.
Blocking the Numeric Keys You can block the numeric keys by setting the appropriate menu code. Numeric keys Blocked Accessible Code 2 5 2 5 1* 2 Important Note: A control command can be input via the balance interface to block the function and numeric keys (except for e). For more information, see part 4. Power-On Mode Depending on the operating mode – line current, battery operation or continuous operation – you can change the power-on mode of your balance.
Fully Automatic Draft Shield Function You can define the fully automatic draft shield function to meet the most diverse requirements. After you have pressed a function key (or after a control command has been received – see part 4, “Interface Description”), the draft shield will close automatically and the balance will then perform the particular function activated by the key. If code 8 8 2 or 8 8 3 is set, the draft shield will open once the function selected has been performed.

You can also use these programs in combination. How? You’ll discover the ins and outs in the examples described on the next pages. To select an application program or a specific function, set the appropriate code in the menu. Part 2 describes in detail how to set menu codes. Additional settings for running the particular program and displaying or printing the data on hard copy are listed in a table of codes. For your convenience, we’ve indicated all factory-set codes with an “*.
Functions Common to All Programs The f, F and w keys are assigned different functions by the individual programs. The functions assigned to the f and F keys are always identified on the display next to each key. c Key c clears the function of a program you are using and resets the program.
Information and Printouts or Data Transfer The info key i has two functions: – one brief press: – one long press: displays information and prints/transfers stored data; selects the reference percentage or reference sample quantity for weighing in percent, diameter determination or counting; clears the memory in the backweighing mode (for more information, see the descriptions of these programs) Briefly press the i key to select the information function: an “i” will appear on the display.
“EUREKA” Air Buoyancy Correction Program “EUREKA” Air Buoyancy Correction Program Code 2 1 8 Symbol displayed: +/– Key identified by: – STO - F when the air density is 1.2 kg/m3 – STO ● - F when the air density is different from 1.2 kg/m3 * Because of air buoyancy, samples or objects with the same mass but different densities have different weights.
The following diagram shows the required corrections of mass values ∆m for a few selected density values ρW. The incorrect values result from the effects of air buoyancy. The corrections depend on the weights displayed on the balance. Correction of the mass ∆m (milligrams) g ρw = 0.8 —– cm3 g ρw = 1.4 —– cm3 g ρw = 2.0 —– cm3 Density of the object to be weighed Add the mass error to the weight displayed on the balance g ρw = 1.0 —– cm3 g ρw = 4.0 —– cm3 g —– cm3 g ρw = 22.
Changing the Density of a Sample Enter the density of a sample using the numeric keys and then confirm this value by pressing the F key identified by “STO.” Afterwards, the density that you entered will be shown in the application display. This density is used to calculate the absolute mass of the sample on the balance. The density must be entered in grams per cubic centimeter (g/cm3). A density may not be greater than 22.5 g/cm3 or less than 0.1 g/cm3.

Air Density Determination For highly precise analyses, the balance offers you a function with which fluctuations in the air density can be determined. ! The air density at the place you set up your balance can be determined within the range of 1.0 kg/m3 and 1.4 kg/m3. For determining the air density, use the special weight set which is available as an accessory (see also part 5, “Accessories”). This weight set consists of one steel and one aluminum weight.
The air density is calculated according to the following formulas: Formula 1: ρL = Air density in kg/m3 ρL = ma * WS – mS * Wa ρS = Density of steel in kg/m3 ––––––––––––––––––– mS = Mass of steel –––––––– – ––––––––– WS = Measured value of steel ma * WS mS * Wa ρa ρs ρA = Density of aluminum in kg/m3 mA = Mass of aluminum WA = Measured value of aluminum Formula 2: 1.2 1 – –––––– 8000 mS = MS * –––––––––– 1– Formula 3: 1.2 MS = Conventional mass of steel ρS mS = Mass of steel –––– 1.
Activating the Air Density Determination Function Hold down the tare key for more than 2 seconds until “C.I.” and “CAL” are displayed next to the f key. To activate the air density determination function, press F, identified by “v,” several times until “A.d.” is displayed. “A.d.” stands for “air density.” Unload the weighing pan and tare the balance. Starting Air Density Determination To start air density determination, press the f key when the display shows a zero readout.
Using the Weight Set for Air Density Determination – Steel Weight – Use the numeric keys to enter the exact mass value specified for the certified steel weight (e.g. 4.999990) and store this value by pressing the f key identified in the display by “STO.” If you press f, identified by “STO,” without making a numeric entry, the display changes to the density readout. Now you can change it for a special steel weight. Enter the mass value and press f to define this density.
– Aluminium Weight – Use the numeric keys to enter the exact mass value specified for the certified aluminum weight (e.g., 5.018072), and store this value by pressing the f key identified in the display by “STO.” If you press f, identified by “STO,” without making a numeric entry, the display changes to the density readout. Now you can change it for a special aluminum weight. Enter the mass value and press f to define this density. Center the aluminum weight on the weighing pan and close the draft shield.
Differential Weighing and Backweighing Differential Weighing and Backweighing Code 2 1 6 Symbol displayed: % S The purpose of this application is to weigh a certain sample in original condition and then after treatment, such as drying, to determine the difference between the two weights and the remaining sample quantity. This is done either in percent or in a weight unit. For each sample, the net weights are compared with each other, since the tare weights are stored first and later subtracted.
Weighing Sequence Individual or Combined Weighing Mode Individual Weighing Mode 1 2 In the individual weighing mode, the weights are stored in the following sequence: – Tare weighing – weighing-in – backweighing – If necessary, selection of an available memory location – Tare weighing – weighing-in – backweighing... The data of a sample in a memory location are overwritten until a new memory location is selected.
After each weighing-in operation has been completed, the next memory location is automatically selected. To proceed from weighing-in to backweighing, you must select the corresponding memory location ID by entering the appropriate number and pressing the F key.
Selecting the Memories Use the numeric keys to enter any memory location ID number up to “50.” Press the F key to have your entry accepted and shown in the application display (in the upper, right-hand corner). At the same time, the weight readout will reappear. Number of Sample Data Stored in a Memory Location One memory location can store the following data for a sample: – Tare value identified by tAr – Net initial sample weight identified by NEt – Net sample residue (backweighed qty.

Procedures for the Individual Weighing Mode Tare Weighing Symbol displayed: Net Key identified by: ● - F Press the F key identified on the display by “●” to accept and store a weight as the tare value. The tare weight will be stored only if the balance has stabilized. At this point, the balance display is zeroed. After tare weighing, the net weight of a sample is determined. The ID code of F in the display changes from “●” to “STO.” Afterwards, weighing can be done starting from “zero.
The calculated value is locked into the display once the sample residue has been stored. To “unlock” this readout, press RE S v - F or select a different memory location using the numeric keys and F. Afterwards, you can proceed with the next tare weighing. A stored value of a backweighed sample can be overwritten with a current value anytime after the corresponding memory location has been selected. To do this, press c. A backweighing operation is done in reference to the original sample weight (= 100%).

Density 1) Density Code 2 1 7 Symbol displayed: ◆ Key identified by: STO - F You can determine the density of solid, liquid and powdery samples according to one of two methods: – Buoyancy method – Specific gravity bottle method The Achimedean principle is applied to determine the volume of a particular sample; this volume is necessary for calculating the density.
Use in Combination with Other Programs You can use a density program in combination with other application programs assigned to the f key. This means you will have all functions of the combined programs available in addition.
You have the following input options: 1) You can directly enter the density of a liquid. In this case, you will not be prompted to enter a temperature (1st function). Enter density using the numeric keys; press F to store. 2) You can enter the density of a liquid at 20°C and the volume expansion coefficient. During density determination, you will then be prompted to enter the temperature (2nd function) (see example below).
Formulas Used to Determine the Density Method Buoyancy: where: Specific gravity bottle: where: Rho = Rhofl Wa Wfl Corr = = = = Wa · (Rhofl – LA) + LA (Wa – Wfl) · Corr LA density of the liquid causing buoyancy weight of the sample in air weight of the sample in liquid correction for buoyancy produced by the immersed wire = 0.99983 = density of air = 0.

Over/Under Checkweighing 1) This program is used to check whether products are within a specific tolerance range, to sort and classify items, and to fill and batch products. Symbols are displayed above the bar graph as visual aids for this type of program: the equal sign indicates the target weight; the minus sign, the underweight limit; and the plus sign, the overweight limit. Within the tolerance range, the response sensitivity of the bar graph is increased. You can define the tolerance limits between 0.

Activation of the Data Output Port Lines You can have different data output port lines – provided by the balance interface – activated according to your requirements by setting the appropriate menu code listed below. For filling, the port lines can be activated regardless of stability. However, for standard checkweighing applications, the port lines should be activated only at stability. This increases the reading speed for an externally connected checkweighing display (YRD 10 Z).
Counting Counting Code 2 1 4 Symbol displayed: P Key identified in the display as follows: – Before the program is selected STO REF - F – During counting OPT - F The counting program allows automatic conversion of weights into piece counts based on a reference sample weight identified by “wRef.
Updating the Reference Sample Accuracy While counting (piece count readout), you can press F identified by “OPT” to update the reference sample for optimizing the accuracy (approx. double the reference sample quantity). In the process, the reference weight (average piece weight) is recalculated based on the total reference sample weight and the piece count displayed. It makes sense to update the reference sample accuracy when the weight of the reference sample quantity is lighter than 100 digits.

Data Input Formats Commands can be input via the balance interface port to control the balance and application program functions. Control commands are distinguished according to those with upper-case letters, or special characters, and those with lower-case letters. Format for Control Commands Control commands can include up to 13 characters. Each character must be transmitted with a start bit, a 7-bit ASCII-coded character, a parity bit and one or two stop bits.
Control Commands with Upper-Case Letters or Special Characters ESC P CR LF Print; stop/start auto print ESC Q CR LF Acoustic signal ESC S CR LF Self-test ESC T CR LF Tare ESC Z CR LF Internal calibration ESC = CR LF Internal linearization The commands “P” through “=” do not affect the code settings of the balance operating menu. The command “S” causes the processor to reinitialize (turns the balance off and back on again).
Control Commands with Lower-Case Letters All functions that can be selected by pressing the appropriate keys on the balance can also be activated by commands.

“Control Error” The control code for “control error” is output if the draft shield door has not reached the selected position after one attempt (for mechanical reasons). yyy = Turning Angle of the Draft Shield The movements of the motorized draft shield door are output as a 3-place decimal number with a position readout. The readout 000 to approx. 360 corresponds to the absolute, counterclockwise position 0° to 360°.
Synchronization and Data Output Parameters Definition During data communication between the balance and an on-line device (computer), “telegram-style” information consisting of ASCII characters is transmitted by the interface. For error-free data communication, the interface parameters including the baud rate, parity and handshake mode, as well as the character format, must be the same for both units.
If the device addressed does not understand the control command, the SBI receiving device continues to operate additionally with a hardware handshake after it has received another 6 characters. For data communication with a software handshake, “XON” must be sent by a device when it is turned on in order to enable another on-line device to exchange data.
Activating a Data Output Process You can define the data output parameter so that output is activated either automatically, or when a print command is received. You have two options for the automatic mode: data output can be either synchronous with the balance display or activated at defined intervals (to select the parameter, see part 2, “Utilities”). Data Output by Print Command The print command can be transmitted by a software command or by pressing the print key.

Special Interface Functions Data Input/Output to/from the Female Interface Connector You can plug an external switch for remote control into the female interface connector (such as foot switch YPE 01 RC with the three functions ”open/close draft shield,” ”tare” and “print” [factory setting]). If you change the menu code setting, you can interface both a checkweighing display (such as our color-coded YRD11Z for OVER/UNDER checkweighing) and our universal remote-control switch to your balance.
Control Lines For classification or filling in the “over/under checkweighing” application program, you can use the voltage levels of four data output port lines to control an external on-line display or control instrument. To activate the control lines, set code 8 7 1 in the balance operating menu. The voltage levels of the data output ports will change according to various patterns, depending on the reference weight and on the lower and upper weight limits.

Setting a Menu Code Turn off the balance; then turn it back on again. While all segments are displayed, briefly press t. If “-L-” is displayed, change to “-C-” using the menu access switch (on the rear panel of the balance computing device).
Adjusting the External Draft Shield Element on MC 210 S, MC 210 P and MC 410 (-0CE) The draft shield consists of two semicylindrical elements. Grasp the lower riffled part of the element to turn it to the position you desire. In addition, you can move the swivel-mounted display to the position you desire (+/– 85°). Adjusting the Aperture Angle of the Draft Shield A narrow aperture angle will reduce the effects of drafts, allowing the balance readout to stabilize faster.
