A&D GX Series Internal Calibration Guide

The A&D GX Series analytical and precision balances include an internal calibration weight that allows quick calibration without external masses.

Procedure
1.) Warm up the balance for at least 30 minutes.
2.) Make sure the weighing pan is empty.
3.) Press the CAL key.
4.) The display shows calibration mode.
5.) The internal mass automatically calibrates the balance.
6.) Wait until END appears.
7.) Return to weighing mode.

Notes
1.) Perform calibration after moving the balance.
2.) Keep the balance vibration free.
3.) Do not touch the weighing pan during calibration.
4.) Use automatic calibration whenever possible.
