Calibrating The Balance; Calibration Using Internal Weight (Calibration Of Balance) - AND BM Series Instruction Manual

7. CALIBRATING THE BALANCE

For details on calibration, read the balance instruction manual in addition to this manual.
Before calibration, refer to "3. PRECAUTIONS BEFORE USE". Because the BM series has an
especially high weighing sensitivity, make sure that the installation environment is appropriate and the
balance is warmed up for the appropriate duration.
7-1 Calibrating using internal weight
With the sample cup holder is set on the balance, it is possible
to calibrate using the internal weight with one touch.
1 Remove only the 5 mL sample cup. In the case of the
BM-20/22, confirm that only the sample cup holder is set
on the balance. In the case of the BM-252/500/300/200,
also install the balance weight on the sample cup holder for
BM.
2 With nothing on the sample cup holder, connect the AC
adapter and warm up the balance for at least one hour.
3 Press the CAL key to display Cal in .
4 The balance performs calibration using the internal mass.
Do not allow vibration or drafts to affect the balance.
5 If GLP output is set,
report is output to the RS-232C interface and is stored in
memory. (For details, refer to "GLP output (info)" and "Data
memory (data)" settings in the function table in the BM series
Instruction Manual.
end is displayed after the calibration.
6 The balance will automatically return to the weighing mode after
calibration.
A calibration test (CC in) and so on can be used to confirm whether

the balance was calibrated correctly. (For details, refer to the BM
series Instruction Manual.)
Note: If you return the normal weighing pan and
calibrate the balance again with the normal weighing pan set.
