General Technical Articles Calibration Weights , Frequently Asked Questions Q. I did the "auto calibration" on the analytical balance . But when I check it with my weight, it still isn't right. I know my weight is accurate, since it's class 1, and we just had it calibrated. What can the problem be? A. Your weight is erroneous, even though it's just been calibrated. Class 1 weights have errors just like all other weights, and those errors are easily measured on an analytical balance.
Q. If all weights are erroneous, how can I ever check the accuracy of my balance? A. You'd have to have a calibration certificate for the weight. This would NOT be a certificate that just says that it’s been checked and that it is within class 1 tolerance. It WOULD BE a certificate that says what the actual weight value is – gives you a number.
Q. If weights wear, how can I be assured that my weights are accurate, even if I get a calibration certificate? A. Only through meticulous care of the weight - protecting it from abrasion and corrosion. For critical weights, never slide the weight across the weighing pan. Instead, rest it gently at exactly the place on the weighing pan you want it to be (the center). Use a lifting tool or a cotton glove to handle the weight, never bare hands.
Drifty Analytical Balances Definition: An analytical balance is one that measures to a ten-thousandth (.000 1) or hundred-thousandth (.000 01) gram. Capacity is in the range of 30-200 grams. These instruments have sliding glass doors to prevent air drafts. Users and technicians often encounter units which are unstable or drifty. Often, it's not apparent whether the source of the instability is an instrument malfunction, or is caused by some environmental influence around the instrument.
Linearity Two mistakes are often made when testing lab balances. The result is that instruments are removed from service unnecessarily. The problems are (1) linearity, and (2) instability, or drifting. This article pertains to linearity testing, and how to properly test it. See the companion article Drifty Analytical Balances for information about unstable analytical balances. The word linearity refers to consistent (equal) sensitivity throught the range of weighing capacity.
Appraising the Condition of Lab Balances When the technician encounters an instrument which is not performing accurately, or is completely non-functional, then there may be a request to speculate what is the cause of the malfunction. The following list associates functional errors with conditions which may be the cause. Since electronic circuits are complex, and their failure modes varied, there is seldom a certain cause for a given malfunction.
Cornerload Cornerload refers to an instrument's ability to indicate consistently at all positions within the weighing pan. Generally, it is adjusted by observing readings as a test weight is re-positioned across the weighing pan. Adjusters, which vary the vertical position of the flexible arms (guides, flexures, etc.) are used to compensate the errors.
"Monobloc" Cornerload Adjustment Several manufacturers now use one-piece cells, fabricated from a single aluminum block. Although this might be cheaper to manufacturer, the result is a cell structure that can only be adjusted for cornerload by filing away the flexible sections. If the flexible sections are distorted by accident or by overloading, the whole cell has to be replaced, generally at huge cost. Do NOT file right on the outside edge of the monoblock Do NOT try to use a flat hand file .

The Force Restoration Principle There are two types of weight detecting mechanisms in common use within scales; strain-gauge based load cells, and the feed-back dependent force restoration cells. Strain gauges are limited in their accuracy to about 1 part in 5000, because the resistive elements and the substrate itself have non-linear effects.
Packaging Lab Balances for Shipment Top Loader Types – Use a box with room for at least 3 inches of cushion material on all sides , more if possible. If possible, double-box. If the instrument uses a wall-mount AC adapter, include it with the instrument, but in a location where it can do no damage if it moves. Don’t send ordinary 120 volt power cords. Include the IES Return Authorization (or a copy) with the instrument.
Static Electricity and Drifty Lab Balances A lot has been written about static electricity and it's effects on electronic circuits. Let me say at the beginning that this article is NOT about power surges or damage to circuits. It is about the fact that static charges on things like people, plastic articles, and even the object being weighed exert a force, and that many lab balances can readily detect those forces. The result is erratic readings, since the force isn't steady.
Moisture Balances - Practical Considerations Moisture balances are typically used to measure the percentage of moisture in samples. They do so by heating the sample, and automatically calculating the percentage of weight lost throughout the heating cycle. Often, users of these instruments find that a given temperature and time setting on one model of dryer doesn't cause the same percent moisture loss as the same settings on another model.
Standard Field Service We are often asked to provide a description of a standard field service for lab balances. The following pages are our best effort at describing such a service. You are welcome to transcribe the procedure to your own document. It consists of: a. b. c. d. Description of Service. Service Record - a form that can serve as a record of performing the steps.

Test Method - Repeatability Select a single test weight of nominal value at least 50%, but not more than 100% , of the weighing capacity of the instrument. Start with the weighing pan empty. Rezero. Alternately place and remove the test weight ten times. If the instrument reproduces both lower and upper readings with variation less than the allowed tolerance all ten times, then the instrument passes the repeatability test. Poor repeatability can be caused by an inadequate operating environment.
Test Method - Cornerload 1. Select a single test weight of nominal value at least 50% , but not more than 100%, or the weighing capacity. 2. Place the test weight in the center of the pan, then rezero. 3. Move the test weight so that it's center is half way from the center of the pan to the periphery at the front, right, rear, and left. 4. Verify operation to be within tolerance. Verify performance on the Service Record , or if required, on the Standard Test Numerical Record. 5.
Test Method - Linearity 1. Select two weights of standard nominal value as close as possible, but not greater than, one-half the weighing capacity of the instrument under test. Segregate these test weights as weight A and weight B. It is permissible to use a group of weights, rather than a single weight, to represent weight A. 2. Place weight A on the weighing pan. Record the reading. 3. Replace weight A with B, and rezero. 4. Place weight A on the weighing pan with B. Record the reading. 5.
Standard Span Test Procedure 1. Select a standard test weight of nominal value as close as possible, but not greater than, the instrument weighing capacity. 2. Place the test weight on the weighing pan. Adjust as required to bring performance within tolerance. Verify performance on the Service Record, or if required, on the Standard Test Numerical Record.

HA Series Calibration / A&D Introduction: There are several aspects to calibrating the HF series. It will calibrate automatically when it senses a temperature change (self calibration ) , or a calibration using the internal weight can be actuated by pressing the CAL button(internal calibration), or the instrument can be calibrated using an external weight(external calibration).
HF Calibration & Linearity / A&D Introduction: At any time during this procedure, if xxx shows on the display, then it is extremely import that the instrument not be exposed to vibration, air drafts, or other factors that would effect the stability. If the instrument shows "Error 1", then the instrument has detected enough instability that it will reject calibration . Calibration 1. Start with the weighing pan empty and the instrument stable. Press and hold RE-ZERO .

CAHN Packing and Unpacking Cahn Microbalances Cahn balances use tiny metallic wires to suspend the weighing pan. These wires are called "hangdowns", and they are quite delicate. During transportation, they are free to move (unless restrained), which can cause any of several problems. Rather than leave them free, restrain them as follows: 1) Cut one 8 inch length of mono-filament thread (fishing leader is great) for each hangdown.
21 23 25 Calibration - Cahn The Cahn microbalances use a balanced beam. The balanced nature of the sensing mechanism makes it essential to have two pans on the instrument during weighing. The pans must be nearly equal in weight. Positions A and B are for the item being weighed, position C is for the counterbalancing pan The various ranges of the instrument do not have separate calibrations. Each time the range is changed, the calibration needs to be performed again.

TL, DTL, 7xxx, 8xxx ,M, MX - how to tell what's what (These are older instrument - from the 1980s) . Not all instruments of every model of DIC instrument are identical. DIC has changed construction methods within some model names. So individual examples of some models will be different in internal construction, even though the external appearance is similar. IES has found that certain characteristics of individual instruments are representative, and attention to them will assist in calibration.

TL Calibration and Password ( new TL series ) – Denver Instrument Denver Instrument Company (DIC) made a series of instruments with “TL” prefix years ago. You can tell the old TL from the new TL because the new TL’s model number implies the capacity and resolution. For example, TL403 is 400 gram capacity and 3 decimal places to the right of the decimal. TL4102 is 4100 gram capacity and 2 places to the right of the decimal.

TR Calibration and Password – Denver Instrument The instrument will calibrate using standard mass values as indicted in the table below.
XA series -- Calibration and Linearity / Denver Instruments Special Note: Not all XA instruments have the ability to adjust linearity and calibration under software control. When the instrument powers up, the software revision will be shown. Those with revision H or latter will have software adjustment capability. Calibrate Press “AUTOCAL”, the internal mechanism uses the internal weight to calibrate.
XA series -- Calibration and Linearity (continued) / Denver Instruments Calibration of Internal Weight Opinion of IES: The procedure outlined in the DIC service manual is hard to understand. We have found that the most productive way to re-calibrate the internal weight is to start by adjusting the “offset” stored in the instrument memory to zero, then adjust iteratively until calibration is correct. You’ll need to record settings and corresponding deviations manually.
XD/AC -- Linearity / Denver Instruments This procedure adjusts the XD linearity. Like many DIC products, the weight values at specific steps in the linearity correction are best determined by trial and error. Typical values are no-load, 1/3 capacity, 1/2 capacity, 2/3 capacity, 3/4 capacity, and full capacity. Some instruments may require that the same weight be used twice. Some instruments won't use no-load at LIN 1; instead a weight will be required. There seems to be no method to the madness.
XD-100A and Dual Display Analyticals -- Linearity and Calibration / Denver Instruments Ideally, you should have two ASTM class 1 50 gram weights for this procedure. You can use lesser weights and still get linearity correct (balance software will account for errors in the weights), but you still need and accurate 100 gram weight at the conclusion.
XL/AL Series -- Calibration and Linearity / Fisher/Denver Instrument The model number implies the capacity and preferred calibration weight for the unit. For example, and XL-400D should calibrate with a 400 gram weight. Under some circumstances, you may want to calibrate at some point other than full capacity. The instrument's microprocessor has been programmed to determine what the calibration weight is, and calibrate to that value.
XP Calibration Within the XP series, there are two general types of instruments. These are distinguished by whether they have four or six buttons on the front panel. Within either of those groups, there are several models. Be sure to use instructions for the appropriate group. Calibration Four button ( -0- ,* , ↓ , I/O ) 1. With pan empty , rezero by pressing -0- . 2. Press the * button for 3 seconds. The display will show "Unit". 3. Press and hold the * button until "CAL" show on the display . 4.
XT and Z Series -- Calibration / Denver Instruments HELP DIC has installed a help menu system IN THE ROM of the instrument. If you have questions about particular key functions on the panel, just push the HELP button. The display is alphanumeric, and will instruct you on how to get the information on the particular function you are interested in. Try it. CALIBRATE The instrument microprocessor will detect and distinguish between calibration weights in even fractions of the over-all range.
XT and Z Series -- Linearity & Calibration / Denver Instruments *** Linearity *** Preface: There are several different XT instruments; different in construction but all called XT. Some XT's have a linearity pot, located on the rear panel. If there are two pots, the top one is linearity. If there is one pot, then it is NOT linearity, and the following instructions apply: 1 TARE 2 Press "SET UP" , then the "." key. LIN1 will be displayed. 3 Wait for a stable number ("g" indicated), then press ".
XT Series -- Linearity and Calibration (continued) / Denver Instruments *** Calibrate *** 1 Place a weight near the capacity of the instrument on the pan. (example: XT7K - 5 Kg calibration weight) The instrument will read erroneously, since it is not calibrated. 2 Push "AUTOCAL" The instrument will read 5000.0 Calibration is now complete. Note the instrument's microprocessor has detected that the calibration weight is near 5000, and therefore calibrates the instrument to read exactly 5000.
8301 -- Instructions For Operating In Counting Mode / Denver Instruments 1) Have a sample of the item to be counted on hand. 2) Plug in balance, turn on, let warm up. 3) Push "Func" button repeatedly until "U" appears. 4) Push "TARE" continuously until P-CAL-1 appears. 5) Place the sample item on the pan. 6) Instrument is now in the counting mode. 7) If it is desired to make the reference count a number other than one (step 4) , such as 10 or 50, then have that group of parts available at step 4.
METTLER AC and PC -- Calibration and Linearity / Mettler The PC group (includes AC-88 and AC-100) encompass a wide range of capacities and resolution, from 80 grams to 24 Kg. The top loader types, (with chassis about 11" deep by 7" wide by 4" tall) have the circuit board on the right side of the instrument, running from front to back. There are four pots on that main board. The calibration pot is mounted on the main board, but is accessible through a hole near the right rear upper corner.
AE-160/163 -- Calibration / Mettler 1) Plug in the balance, turn it on, and let it warm up for at least 5 minutes. Level the balance. The balance must remain stable throughout the entire calibration sequence. Instability is indicated by a decimal point in the left bottom corner of the display. 2) Be sure the calibration lever (right side of instrument, on the bottom), is in the forward position. 3) Push the "TARE" bar until "CAL ---- " appears on the display.
AE -- Linearity / Mettler Hazardous electric circuits will be accessible during this procedure. This procedure is for qualified electronic technicians only. Mettler specifies two 80 gram weights for linearity adjustment. However, it is possible to use, for example, a 50 gram and a 100 gram weight. The internal calibration weight can serve as the 100 gram, so only one 50 gram external weight is then required.
AE Display board exchange The AE series have display boards that are easy to exchange. This is useful because the board itself is prone to several problems, notably a dimming of the displayed numbers. A replacement display board returns the unit to service with bright , clear numbers that will last for many more years. To exchange the display, proceed as follows: 1. Unplug the instrument 2. Slide the glass doors open and remove the weighing pan. 3.
AG -- Calibration and Menu / Mettler Mettler's AG style analytical balance calibrates from the front panel. There is no linearity adjustment without the special service software and circuit board, which Mettler-Toledo doesn't sell. Calibration (SPAN) 1 Allow the unit to warm up. Analytical balances need to operate continuously, and in an environment that is temperature regulated continuously. 2 Push and hold the 1/10d button until CAL Int shows on the readout, then release the button.
AK, PK, and HK -- Calibration / Mettler This was Mettler's first instrument to use software calibration. Accordingly, it is somewhat less "user-friendly" than their latter versions. If the instrument has any external devices connected (printer, etc.), then you MUST disconnect it prior to calibration. The awkward part of this procedure is that the instrument will reject a calibration (indicated by "CAL Err") if any of these criteria are not met: a. Stability indicator must be extinguished. b.
AK, PK, and HK -- Calibration (continued) / Mettler Linearity All of the K series instruments use similar cells, connected to various mechanisms to result in various instrument capacities. Since the cells are similar, the method of adjusting linearity is the same for all. At the rear of the cell, notice four 3MM hex-head screws. The outer ones adjust cornerload by moving the "termination" of the guides vertically.
AT -- Calibration and Calibration Mode Selection / Mettler Background: 1 The Mettler user's booklet is highly recommended to anyone attempting to use the instrument's programmable functions. 2 The instrument has 3 modes of calibration: internal automatic, internal non-automatic, and external. The three are mutually exclusive. One of the three modes must be functional. The selection of the calibration mode is a separate process from actually performing the calibration. Calibration Mode select: a.
AT -- Packaging and Glass Doors / Mettler Warning Mettler uses specially shaped glass doors on these instruments. Unless the instrument is shipped using the precautions below, the glass doors will almost certainly be broken. Cost of doors and glass alone is in the vicinity of $1000. IES does not need the glass to repair the instrument, so please do not ship it to us. Please call us before you ship these instruments. Remove glass: 1) Find a box to keep many small parts in.
BD Calibration Required calibration weights: BD202 200 g BD601 500 g BD1201 1000 g BD6000 4000 g 1. Warm up instrument at least 1 hour. Lab balances work best is an environment which is temperature controlled continuously. 2. Remove all objects from the weighing pan , then tare to zeros. 3. Press and hold the Cal/Menu button until CAL appears on the readout, then release CAL/Menu. 4. After a stabilization period, the display will start flashing. Add the required calibration weight. 5.
BB -- Service / Mettler Calibration / Span Plug in and power ON. Empty weighing pan. Tare to zeros. Press and hold REZERO until CAL shows on the display, then release REZERO. When the readout displays a blinking number, put that calibration weight on the pan. Wait for blinking zeros, then remove the calibration weight. The pan is now empty. The instrument returns to normal operating mode automatically. Linearity There is no linearity adjustment potentiometer.
HL Balances -- Checklist for Shipping / Mettler The following checklist will assist with packing Mettler HL balances. When these steps are taken, the chances for damage are reduced. ( ) Remove the pan, pan brake, and pan brake cover. Place them in a that they cannot break glass during transit. separate box or bag so ( ) Tape the sliding glass doors in the open position, so that they are protected by the metal sides of the balances. ( ) Notice the gold hairwires towards the rear of the beam.
LJ16 and LP16 Infra-Red Dryer / Mettler START key - Starts all drying operations. Lighted & flashing - ready. Lighted steadily - Drying It is NOT possible to start drying without a sample on the weighing pan. STOP key - Stops any operation. Change Temperature: (Must be done PRIOR to starting dryer) 1 - Press "Thermometer" key. 2 - Press up or down key to adjust temperature. 3 - Finalize temperature selection with "ENTER" key.
ME30 This instrument weighs to a millionth of a gram - a microbalance. The knob on the right side (arrestment knob) sets the instrument to one of three modes. Use position 0 (arrested) when adding or removing items from the weighing pan. Release the instrument to position 1 for weighing. If the instrument needs to be moved, use position T. When you move any weight dial or the arrestment lever, do it slowly and gently. These instruments demand a very good environment for best performance.
M3 -- Calibration / Mettler The Mettler M3 microbalance is a substitution type of balance. The electronic weighing range is .1 gram. For unknowns greater than .1g, the knobs on the left are dialed to within .1 g, which adjusts internal weighs accordingly. These are extraordinarily sensitive instruments.
M3 and UM3 microbalance - packing for shipment Call IES for one of our specially made analytical boxes. It's the best way to take care of the instrument in transit. It’s worth the wait. The box is free and we pay the shipping via UPS surface. If you want express shipping, we will ship it on your account. 1) On the front of the instrument, there is a glass plate held on with screws. That plate should be removed prior to packaging. Don’t ship the glass, washers, or screws with the instrument.
MT5 UMT5 Calibration The following procedures presume that the instrument is configured under standard factory settings. If not, then the procedures will be different. For a complete copy of the Mettler user manual, visit the Mettler lab website at mtlabservice.com A. Calibrate using internal weight 1. Repeatedly press the MENU key until AUTO CALIN CAL INT shows on the readout. 2. Press the SET key. 3. The draft shield will close automatically unless it has been disabled via the program menu.
PB / AB / SB Calibration - Mettler (new style) Introduction Configuration and calibration of these instruments is accomplished through the front keypad. Each key has two functions, depending on whether it is pressed momentarily, or pressed and held. Further, the keys will have a different function when in normal operating mode than when in a configuration-menu setting mode. The function marked in white lettering directly on the key is activated when the key is pressed and immediately released.
Linearity Linearity is not adjustable in the field. Call IES at (800) 541-0852 .
PB -- Calibration / Mettler (old type) Mettler has produced TWO series of instruments with the “PB” designation. This note applies to the older series ( PB30, PB300, PB3000, all with red LED type displays ). If the model you have isn't one of these, then it's the new type.
PB (old style) and PL Instruments -- Installation of HDSP / Mettler Replacement of digital display LED's The PL and PB instruments used Litronix DL-721 and DL-727 display devices, which are no longer manufactured. Hewlett Packard 's HDSP-5321 and Quality Technology MAN6910 are pin compatible with DL-727, but have slightly larger numerals. There is no substitute for the DL-721.
PC -- Temperature Compensation / Mettler 1. Adjustment of temp. comp. is required ONLY when a main board or measuring cell is being replaced. The reason is that the cell and board have to be matched. If an instrument is drifty, it's probably because of a mechanical or electrical defect, and that will not be corrected by adjustment of temp. comp. Adjusting temp. comp.
PC -- Temperature Compensation (continued) / Mettler 5. Notice that, when doing calibration temp. comp., you can get readings as the instruments warms or cools. YOU MUST take a new reading of the calibration after adjusting the pot, since the setting of the pot effects the calibration. 6. Use a similar chart for zero-point temp. comp., but there will be no weight on the pan during the adjustment procedure.
PC -- Calibration and Linearity / Mettler The PC group (includes AC-88 and AC-100) encompass a wide range of capacities and resolution, from 80 grams to 24 Kg. The top loader types, (with chassis about 11" deep by 7" wide by 4" tall) have the circuit board on the right side of the instrument, running from front to back. There are four pots on that main board. The calibration pot is mounted on the main board, but is accessible through a hole near the right rear upper corner.
PC2000, PC4000, PC4400 -- Guides Made By IES Corp. Mettler no longer sells the former 41189 part; upper and lower guide for the popular PC2000/4000/4400 series of instruments. However, these instruments can be salvaged when guides are broken. IES makes a replacement guide that can return the unit to full performance operation. An exchange program allows technicians to replace damaged 41189s in the field.
PE Lab Balances -- Calibration / Mettler With the exception of the PE-200,2000,400, and 4000, the Mettler PE group calibrates by placing a calibration weight on the pan, after initiating an automatic calibration cycle. The 200/2000/400/4000 group is calibrated manually by means of an adjusting screw at the right front corner. To calibrate PE instruments (other than 200 etc.) , proceed as follows. 1 Plug in the instrument and warm up at least 10 minutes.
PE -- Pots & Boards / Mettler There are many instruments in the PE series, with resolution from .001 gram to 1 gram. Many individual models use the same circuit boards as other models in the series, but many are different too. Be especially careful NOT to interchange boards between different models unless both are using the same part number of board (as indicated on the yellow tag, on the underside of the board).
PK, AK, HK -- Calibration / Mettler This was Mettler's first instrument to use software calibration. Accordingly, it is somewhat less "userfriendly" than their latter versions. If the instrument has any external devices connected (printer, etc.), then you MUST disconnect it prior to calibration. The awkward part of this procedure is that the instrument will reject a calibration (indicated by "CAL Err") if any of these criteria are not met: a. Stability indicator must be extinguished. b.
PK, AK, HK -- Calibration (continued) / Mettler Linearity All of the K series instruments use similar cells, connected to various mechanisms to result in various instrument capacities. Since the cells are similar, the method of adjusting linearity is the same for all. At the rear of the cell, notice four 3MM hex-head screws. The outer ones adjust cornerload by moving the "termination" of the guides vertically.

PR / SR Calibration - Mettler These instrument are normally (factory default) configured to utilize internal calibration. Unless they have been re-configured, this is the configuration instruments will be found in. Introduction The keypad of the PR/SR instruments has several keys, as well as a series of horizontal lines just below the readout. Keys which have green lettering have two functions. The primary function is symbolized by the white lettering, and is actuated by briefly pressing the key.
PR Calibration adjustments, continued External Calibration Calibration to an external standard requires that the instrument menu system be accessed to put it into this mode. When using the menu system, selection choices will appear on the digital readout. Select a single choice by pressing the key directly below it . ( NOTE: Sometimes, not all choices are visible, since they don't fit on the alpha-numeric display.
PT Calibration & Cornerload adj (Old-Style Mettler PT) Warning The instrument has two covers; one over the front (gray), and one over the rear (black). This warning pertains to the front. If you need to remove the front cover, be sure to detach the pan and its sub-pan, prior to loosening the cover. This front cover slides as it is removed, and will push against the pan stems unless the pan is removed first.
Installation of PML4 Linearity Board / Mettler The PML4 board is an add-in board, which gives PM and PJ instruments a linearity potentiometer. This board fits in instruments with chassis size of approximately 12" x 8". Linearity adjustment is often required after replacement of a front coupling. No electronic adjustment or circuit can compensate a damaged cell, or one which has been assembled incorrectly. To successfully install the PML4, you'll need excellent soldering and desoldering skill.
PML4 Linearity Board Installation (continued) / Mettler PM Toploader Balance Locate the CALIBRATION RESISTORS, just in front of the PML4. They are soldered onto metal posts, just in front of the board you are installing. Bend the bare wire to the inner stake of the front resistor, then solder. Remove any excess wire. Re-install the main board, with 3 screws. Connect all cables. Install display board. Put on the pan and power up.
Installation of PML1 in High Capacity Instruments / Mettler The Problem The PML1 board was designed to fit PM/PJ top-loaders. It can't be installed DIRECTLY into a high-capacity instrument such as PM-30, because Mettler uses a different section of the LM358 IC for the integrator in the high capacity instruments The Cure 1 If you're not a skilled electronic technician, you probably shouldn't try this. 2 Several main boards exist for the large PMs, and not all are documented by Mettler.

B-1500A -- Calibration / Ohaus 1 The B-1500 A has two calibration (span) adjustments. The COARSE adjustment is done with switches on the display board. The chart below details the calibration range available from various switch settings. 2 FINE adjust is located on the REAR PANEL, towards the top. Due to the range of adjustment available, it is normally the only calibration adjustment needed.
B3000 -- Calibration and Linearity / Ohaus Like other Ohaus B series balances, the B3000 has both a coarse and a fine calibration adjustment. Normally, only the fine adjustment potentiometer is required. In situations where the calibration can not be set accurately with the fine potentiometer, the coarse calibration switches must be reset. The fine adjustment pot is located on the front panel, above the TARE bar.
E Series -- Calibration and Linearity / Ohaus Ohaus's E series instruments (E3000D, etc.) are calibrated from the front panel. Neither sensitivity (span) nor linearity require removal of the instrument cover. The following instructions pertain to E3000. Other E series instruments (different capacity) will require different calibration weights. Calibration 1 Turn the instrument ON. 2 Push and hold the ON button until - CAL - is seen on the display, then release the ON/TARE button.
G and GT Series -- Linearity and Calibration / Ohaus The Ohaus G and GT instrument use a series of slide switches on the main board to enable/disable the linearity correction feature. When enabled, the SPAN adjustment will call for intermediate weights, and make corrections for linearity automatically. There is no linearity pot. Before changing the position of the switch that enables this capability, UNPLUG the instrument.
