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
The internal mass
The normal range
BM-20, BM-22
20.00000 g
±0.15 mg
BM-252, BM-200, BM-300, BM-500
200.0000 g
±1.5 mg
Example: 200.0000 g is corrected to +0.6 mg (200.0006 g). When using a 100 g external weight by
+0.6 mg for the correction, and the weight changed to 200 g, the correction value is +1.2 mg.
1 Perform one-touch calibration. Weigh an external weight and get the correction value.
