8.4. Calibration Test Using the Internal Mass
This function tests the balance accuracy using the internal mass.
This is available only when the "GLP output (info)" parameter is set to "1" or "2".
Calibration test does not perform calibration.
1 Connect the AC adapter and warm up the balance at least one hour.
2 Refer to "10. Function Table" to set "GLP output (info)" to "1" or "2".
3 Press and hold the CAL key until CC in is displayed,
then release the key.
4 The balance measures the zero point.
Prevent vibration and drafts to affect the balance.
5 The measured zero point data is displayed.
6 The balance measures the internal mass.
Prevent vibration and drafts to affect the balance.
7 The value of the internal mass is displayed.
The normal range of the value is as follows:
Model The internal mass The normal range
BM-20, BM-22 20.00000 g ±0.02 mg
BM-252, BM-200
BM-300, BM-500
200.0000 g ±0.2 mg
8 glp is displayed and the calibration test report is output
to the RS-232C interface and is stored in memory. Refer to
"GLP output (info)" and "Data memory (data)" of the
function table, "11.2. GLP Report" and "12. Data
Memory".
end is displayed after the calibration test.
9 The balance automatically returns to the weighing mode.
