When To Calibrate; Calibration Using A Calibration Weight - A&D SJ-1000H Instruction Manual

When to Calibrate

Calibration may be required when it initially installed or it is moved a
substantial distance. Also periodical calibration will be recommended.

Calibration using a Calibration Weight

1. Enter calibration mode.
Press the [ON/OFF] key to turn the power off. While
pressing both the [RE-ZERO] and [UNITS] keys,
press the [ON/OFF] key.
Or remove the calibration switch cover on the bottom
and press the calibration switch while in the weighing

Calibration by Gravity Compensation
The scale is calibrated at 9.798 m/s
gravity at your location is not same and if you do not have calibration
weights, you can calibrate the scale by compensating the acceleration of
gravity. (Refer "The Value of Gravity at Various Locations".)
