8-3. One-Touch Calibration
Calibration using the internal mass
This function calibrates the balance using the internal mass. The only operation required is
to press the CAL key.
Step 1 Connect the AC adapter and warm up the balance for at least 30 minutes with
nothing on the weighing pan.
Step 2 Press the CAL key.
Step 3 The balance displays
Calin and performs calibration using the internal mass. Do
not allow vibration or drafts to affect the balance.
Step 4 The balance displays
end after calibration. If the "GLP output (info)" parameter of
the function table is set to "1" or "2", the balance displays glp and outputs the
"calibration report" using the RS-232C interface or stores the data in memory. Refer
to "11-2. GLP Report" and "Data memory (data)" of the function table for details.
Step 5 The balance will automatically return to the weighing mode after calibration.
About the internal mass
The value of the internal mass may change due to aging, corrosion or other damage caused
by the operating environment. Check the internal mass periodically. Correct the internal
mass value as necessary. Refer to "8-6. Correcting the Internal Mass Value".
To maintain the weighing accuracy, perform the calibration using an external weight
periodically, as described below.
