1. Introduction This manual describes how the MC Series Mass Comparator Balances, MC-10K and MC-30K, work and how to get the most out of them in terms of performance. Read this manual thoroughly before using the balance and keep it at hand for future reference. For other functions and operations that this manual does not describe, refer to the GX-K series instruction manual. 1-1. About This Manual This manual consists of the following five parts: Basic operation ........................
1-3. 1-3-1. Compliance Compliance with FCC Rules Please note that this equipment generates, uses and can radiate radio frequency energy. This equipment has been tested and has been found to comply with the limits of a Class A computing device pursuant to Subpart J of Part 15 of FCC rules. These rules are designed to provide reasonable protection against interference when equipment is operated in a commercial environment.
2. Unpacking And Installing The Balance The balance is a precision instrument. Unpack the balance carefully. Keep the packing material to be used for transporting the balance in the future. The packing contents depend on the balance model. See the illustrations to confirm that everything is contained. Weighing pan Pan support Handling hole A clear display cover Bubble spirit level Display Keys Reference card Leveling foot Draft gate Remove the gate when cleaning.
2-1. Auto-centering Pan (AX-MC10K/30KPAN) Installation Procedure Caution: During installation, do not to apply excessive force to the balance. When used as a mass comparator, the balance can achieve even more precise weighing, by using the auto-centering pan (sold separately), which reduces eccentric loading errors. 1. Place the pan support on the balance. Place the breeze break provided with the AX-MC10K/30KPAN option on the balance.
2-2. Installing the Balance Install the balance as follows: 1 Refer to "3. Precautions" for installing the balance. Bubble spirit level 2 Install the pan support, weighing pan and draft gate. Refer to the previous page. Good 3 Adjust the leveling feet to level the balance. Confirm it using the bubble spirit level. 4 Confirm that the AC adapter type is correct for the local voltage and power receptacle type. 5 Connect the AC adapter to the balance firmly. Earth the balance.
3. Precautions To get the optimum performance from the balance and acquire accurate weighing data, note the following: 3-1. Before Use The maximum resolution of the precision balance is ten million counts. Therefore, there are tendencies to be influenced by temperature change, air pressure change, static electrisity, vibration and drafts where the balance is placed. Install the balance in an environment where the temperature and humidity are not excessive.
3-2. During Use Discharge static electricity from the weighing material. When Material case Charged weighing sample (plastics, insulator, etc.) could have a static sample charge, the weighing value is influenced. Ground the balance, and Eliminate the static electricity by using an optinal static eliminator, AD-1683. Grounding Or try to keep the ambient humidity above 45%RH at the room. Or use the metal shield case. Or wipe a charged material (plastic sample etc.) with the wet cloth.
Do not allow the balance to be immersed in water. Even though the balance complies with IP code, the balance will not withstand being completely immersed in water. The weighing pan, pan support and draft gate can be removed to clean the balance. Clean by splashing with water. Use the waterproof option RS-232C cable GX-07K, when RS-232C interface is used with IP-65. AX-KO1710-200, a standard RS-232C cable, is not waterproof or dustproof. 3-4.
4. Display Symbols And Key Operation Key Operations Key operation affects how the balance functions. The basic key operations are: "Press and release the key immediately" or "Press the key" = normal key operation during measurement "Press and hold the key". Displays the highest-order digit when placing a load of 10 kg or more on the MC-10K Display Displays memory data information Displays the weighing data relative to the weighing capacity in percentage, in weighing mode.
5. Weighing Units With the balance, only the unit “g” (gram) was set at the factory. The following weighing units and weighing modes are available for selection: Counting mode g kg DS Percent mode % OZ OZt pcs MS t TL GN ct dwt mom Density mode (To select this mode, press the MODE key until the processing indictor blinks with the unit "g" displayed. " " appears only when the density value is displayed. For details about this mode, refer to the GX-K instruction manual "15. Density Measurement".
The tables below indicate the weighing capacity and the minimum display for each unit, depending on the balance model. When a measurement unit other than gram is used, it is not possible to weight up to capacity of the balance because the display does not have sufficient digits. Use the MC series balance within the values shown in the tables below.
6. Weighing 6-1. Selecting a Weighing Unit (Mode) Press the MODE key to select a unit or mode for weighing. The unit “g” (gram) was set at the factory. To use other units, select and store units and displaying order in the function setting of “ Unit ”. For details on weighing unit storing procedure, refer to the GX-K series instruction manual, “5-2. Chaning the Units”. 6-2. 6-2-1.

F2 M1 M2 When Building into a System z When a special weighing pan is to be designed, the weight of the pan and the material to be weighed should not exceed the weighing capacity of the balance. To reduce influences of static electricity and magnetism, use materials other than resin and magnetic material such as iron.
7. Weighing Speed Adjustment / Self Check Function 7-1. Weighing Speed Adjustment This function detects the influence on weighing that is caused by drafts and/or vibration at the place where the balance is installed and sets the following three weighing speeds (response characteristics) automatically. Weighing speeds 0.000 The function has three rates as follows: g Changing the weighing speed changes the display refresh rate. Indicator FAST MID.
7-2. Self Check Function with Response Adjustment This function automatically updates the response adjustment by analyzing the influence of the environment on the weighing data and also self-checks the balance performance using the internal mass. Press and hold Step 1 Press and hold the MODE key until RESPONSE is displayed, and then release the key. Step 2 The balance automatically starts to check the balance performance and sets the response characteristic.
8. Calibration 8-1. Calibration Group The balance has the following modes as a calibration group.

8-6. Correcting the Internal Mass Value The balance can correct the internal mass value within the range shown below. This function corrects the internal mass value to conform to an external weight. The corrected mass value is maintained in non-volatile memory even if the AC adapter is removed. The internal mass value is corrected as follows: The same mass 10 kg 10 kg Model Target Range Correction the internal mass by +0.30 g at 10 kg. MC-10K 2 kg ±0.500 g Calibrate with the 10000. 0 0 g MC-30K 10 kg ±5.
