8.6. Calibration Test Using An External Weight
This function tests the weighing accuracy using an external weight.
Calibration test report can be output or stored with "GLP output (
info )"
Calibration test does not perform calibration.
1 Connect the AC adapter and warm up the balance for at least
one hour with nothing on the weighing pan.
2 Press and hold the CAL key until CC out is displayed,
then release the key.
3 When displaying CC 0 , proceed as follows:
If the target mass is changed, press the RANGE key and
proceed to step 4. A list of usable weights is on page 31.
If current target mass value is used, proceed to step 5.
4 Specify the target mass value as follows:
RANGE key........ The key to switch blinking figures.
RE-ZERO (+)key... The keys to select the target mass or
adjust the mass value. Refer to page 31.
PRINT key.......... The key to store the new mass value.
Even if the AC adapter is removed, the
data is maintained in non-volatile memory.
CAL key............. The key to cancel the operation and
return to CC 0 .
5 Confirm that there is nothing on the pan and press the
PRINT key. The balance measures the zero point and
displays the measured value. Do not allow vibration or
drafts to affect the balance. The balance displays the
target mass value.
6 Place the displayed target mass on the pan and press the
PRINT key. The balance measures the target mass and
displays the measured value. Do not allow vibration or
drafts to affect the balance.
7
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.
