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:
Model Target
Range
GH-120 100.000
g
GH-200
GH-300
GH-202
GH-252
200.000 g
±1.5 mg
1 Calibrate the balance using the internal mass. (one-touch calibration)
Example: 200.0000 g is corrected to +0.6 mg (200.0006 g). When correcting a 100 g
external weight by +0.6 mg, the weight changed into 200 g, the correction value is +1.2 mg.
