CALIBRATION
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.
The position of the [UNITS] key for the Calibration
The g model has no
[UNITS] key, but the key
used to enter calibration
is located under the
overlay.

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
will be displayed.
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
end
and
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
end
and the scale will
automatically return to the weighing mode.
