Device and Measuring Parameters
APoFF – specified time for automatic shutdown and continuous ON
The instrument is switched off automatically if the measured value
remains unchanged for a long period of time and if none of the
keys or the rotary switch have been activated before the specified
time “APoFF” (entered in minutes) has elapsed.
If the on setting is selected, the multimeter is set for long-term
measurement and
ON appears in the display to the right of the
battery symbol. In this case, the multimeter can only be switched
off manually. The “on” setting can only be cancelled by changing
the respective parameter, and not by switching the instrument off.
