calibration). Then, place an external weight and confirm
the value to be corrected.
In the example, the value is off by -0.006 gram and the

the value is to be corrected by 0.012 gram in 400.000 grams.

3 While pressing and holding the PRINT key and the
SAMPLE key, press the ON:OFF key. The balance
