One-Touch Calibration For The Gx-M Series - A&D GX-M Series Instruction Manual

9-2 One-Touch Calibration For The GX-M Series

This function calibrates the balance using the internal mass.
1. Connect the AC adapter and warm up the balance for at least 30 minutes with nothing on the
weighing pan.
2. Press the CAL key. The balance displays Calin and performs calibration using the internal
mass. Do not allow vibration or drafts to affect the balance.
3. 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 "sensitivity adjustment report" using
the RS-232C interface or store the data in memory. Refer to "12-3. GLP Report" and "Data memory
(data)" of the function table for details.
4. 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 factors such as the operating environment and aging.
Correct the internal mass value as necessary. Refer to "9-6. Correcting The Internal Mass Value Of The
GX-M series", "9-7. Correcting The Internal Mass Value Of The GX-M series (Auto)".
Since the internal mass is about 850g, the possibility of error may increase as the weighing value
incereases.
To maintain the weighing accuracy, perform the calibration using an external weight periodically, as
described below "9-3. Calibration Using An External Weight".
