Correcting The Internal Mass Value - A&D BM series Instruction Manual

Correcting the Internal Mass Value

8.7.
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:
BM-20, BM-22
BM-252, BM-500, BM-300, BM-200
Example: With the BM-300, 200.0000 g is corrected by +0.6 mg (200.0006 g). When performing a
+0.6 mg correction with a 100 g external weight, the correction value will be +1.2 mg in
accordance with the reference value of 200 g.
1 Perform calibration using the internal mass. Weigh an external
weight and get the correction value.
