When To Calibrate; Calibration Using A Calibration Weight - A&D HL-1000WP Instruction Manual

When to calibrate

Calibration may be required when the scale initially installed, if it is
moved a substantial distance, or in accordance with local regulations.
This is necessary because the weight of a mass in one location is not
necessarily the same in another location. Also, with time and use,
mechanical deviations can occur.

Calibration using a calibration weight

Calibrate the scale with calibration weights at full capacity.

HL-3000WP: 3000g ± 0.2g
1. Enter calibration mode.
Press the [ON/OFF] key to turn the power off.
While pressing both the [RE-ZERO] key and the [UNITS] key, press the
[ON/OFF] key. Cal
2. Zero calibration
Press the [RE-ZERO] key to calibrate zero. Cal 0 will be displayed.
Wait for the stable indicator to be displayed and then press the
[RE-ZERO] key.
Cal f will be displayed in a few seconds. If only the zero calibration is
to be done, press the [UNITS] key. The scale will show
automatically return to the weighing mode.
3. Span calibration
Place the weight at the center of the platform for an accurate calibration.
Wait for the stable indicator to be displayed and then press the
[RE-ZERO] key. The display will show
automatically return to the weighing mode.
