7-1. Calibration using a weight
‰ Prepare a calibration weight (optional) before start.
1. Warm up the balance for at least half an hour with
nothing on the pan.
2. Press and hold the calibration (CAL) switch until
Cal appears, and release the switch.
3. The balance displays Cal 0 .
To change the calibration weight value, proceed to
step 4.
To use the calibration weight value in the balance
memory, proceed to step 5.
4. Press the SAMPLE key. The display shows the
calibration weight value in “gram” that is stored in the
balance. Use the following keys to change the value.
SAMPLE key To select the digit blinking to
change.
RE-ZERO key To set the value of the digit
selected.
PRINT key To store the value and return to
step 3.
