10.3.2 PSC Fully-automatic span calibration
(AUW-D/AUW/AUX series only)
Using a temperature sensor, this function performs fully-automatic span calibration with the built-in
weight when a significant temperature change is detected.
If PSC turned ON, when there is a temperature change that would influence sensitivity, span calibra-
tion executes automatically to maintain the sensitivity of the balance. Span Calibration executes auto-
matically in mass display mode under any of the following circumstances.
(1) When there is a change in the surrounding temperature
(2) When about four hours has passed since the previous calibration.
(3) After either condition (1) or (2) above has been met during warm up at stand-by status, when
the balance is switched to mass display mode.
In mass display mode, when any of the conditions above has been met, the weight symbol will blink for
about two minutes as notification of span calibration before calibration begins.
The sensitivity before and after span calibration is slightly different. Also, no measurements can be
made during span calibration. When you wish to avoid entering span calibration in the middle of one
round of measurements, pressing the
[POWER]
key when the weight symbol is blinking will abort the
automatic span calibration.
Note
Using a verified balance as a legal measuring instrument in the EU:
The balance must be used within the temperature range indicated on the
verification label.
When PSC is not activated, operator must carry out span calibration (refer
to
) upon blinking of the Weight Symbol.
Caution
Make certain that no object is on the pan and all the doors are closed during
span calibration. Never cause vibration of the balance during calibration.
