10.3.2 PSC Fully-automatic span calibration
(CAUW-D/CAUW/CAUX 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 calibration executes automatically to maintain the sensitivity of the balance.
Span Calibration executes automatically 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.
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.
