Special Functions
Auto power OFF function
In order to avoid that the operating life of the battery is shortened unnecessarily, an
automatic switch-off function has been implemented. If a button has not been pres-
sed or the rotary switch has not been activated for more than 35 minutes, the mea-
suring instrument will be switched off.
To switch on the measuring instrument again, first switch it off and then switch it on
again in the appropriate measuring range.

The REL function allows a reference value measurement to avoid possible line losses
which may caused e.g. during resistance measurements. For this purpose, the cur-
rent indicated value is set to zero. A new reference value is set.
Press the "REL" button to activate this measuring function. "REL" appears on the
display. The automatic measuring range selection is deactivated now.
To switch off this function, the "REL" button is to be pressed once more.
