7. Programming 7.1.1. Scaling the display range Over- and underflows are displayed as follows: An overflow is displayed as nnnn; this occurs if: • the input signal exceeds the permissible maximum around more than 0,5V or 1mA; e.g. input voltage >10,5 V or input current >21 mA. •...
7. Programming 7.2. Tare function The tare function works as follows: pushing the tare button will store the displayed value in the tare memory. The tare value will be substracted from the measured value. The tare value is stored in an non-volatile memory and will be saved even when the device is switched off.
