ISHIDA MTX-150Kg - MG-3000 Calibration

Industrial Scales 9
2.3 MG-3000
The MG-3000 uses one of two CPU boards. Early versions used the circuit board number P-780; later versions
use the circuit board number P-802. Both function the same, but the calibration and setup procedures differ.
2.3.1 Calibration For Units With P-802 Circuit Board
Follow the steps below to calibrate an MG-3000 with a P–802 circuit board.
Step Action Display
1Turn off the scale.
2Press and hold the ZERO and CHG/VAL keys, then press and release the ON/OFF key.
3 Release the ZERO and CHG/VAL keys. C
4Proceed to Step 10 for calibration only. Continue with the next step for configuration. xxxx
5Press and hold the ZERO key, then press the CHG/VAL key, then release both keys. xxxx
6 Set the country code = 20 (USA): Press the TARE key to change the digit position.
Press the CHG/VAL key to increment the value.
Cb xx
7Press the SET key. Cb 20
8Press the CHG/VAL key to select the capacity: 11 = 15 x 0.005 Lb; 10 = 6 x 0.002 Lb. CAP xx
9Press the SET key. CAP 11
10 With no weight on the scale, press the ZERO key until the display shows 2000 counts. xxxx
11 Place the full capacity weights on the scale as determined in Step 9 above. 2000
12 Press the TARE key. xxxxx
13 The span counts should read 17000 ± 1. If not, repeat the process from Step 10. 17000
14 Remove the brass hex bolt on the rear of the indicator. Use a non-metallic device to press
the memory switch on the circuit board. NOTE: Using a metallic device can damage the unit.
The switch feels like it clicks when pressed.
17000
15 Remove weights, then turn off the scale. 17000
16 Turn on the scale and test the calibration by placing a known weight on the scale.
17 When calibration is complete, replace the brass hex bolt on the back of the indicator.
