..........
The key to switch blinking figures.
RE-ZERO (+)key
.....
The keys to select the calibration mass or

The key to cancel the operation and
return to Cal 0 .
5 Confirm that there is nothing on the pan and press the
PRINT key. The balance measures the zero point.
Do not allow vibration or drafts to affect the balance.
The balance displays the calibration mass value.
6 Place the displayed calibration weight on the pan and press

end is displayed.
Remove the weight from the pan.
8 If GLP output is set, glp is displayed and the calibration
report is output and stored. Refer to "GLP output (info)" and
"Data memory (data)" of the function table, "11.2. GLP
Report" and "12. Data Memory".
9 The balance will automatically return to the weighing mode.
10 Place the calibration weight on the pan and confirm that the
