2.3.2 Calibration For Units With P-780 Circuit Board
Follow the steps below to calibrate an MG-3000 with a P–780 circuit board.
Step
1 Turn off the scale.
2 Press and hold the ZERO and CHG/VAL keys, then press and release the ON/OFF key.
3 Release the ZERO and CHG/VAL keys.
4 Wait for the internal counts to display (usually 6 to 7 seconds).
5 Proceed to Step 11 for calibration only. Continue with the next step for configuration.
6 Press and hold the ZERO key, then press the CHG/VAL key, then release both keys.
7 Press the CHG/VAL key until the country code = 20 (USA).
8 Press the TARE key.
9 Press the CHG/VAL key to select the capacity: b = 15 x 0.005 Lb; A = 6 x 0.002 Lb.
10 Press the TARE key.
11 With no weight on the scale, press the ZERO key until the display shows 2000 counts.
12 Place the full capacity weights on the scale as determined in Step 9.
13 Press the TARE key once.
14 The span counts should read 17000 ± 1. If not, repeat the process from Step 11.
15 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.
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.
