off.
Automatic Shutdown – DMM
The instrument is switched off automatically if the measured value
remains unchanged for a long period of time (maximum measured
value fluctuation of approx. 0.8% of the measuring range per
minute, or 1

C or 1
°
F per minute), and if none of the keys or the
rotary switch have been activated before a selected period of time
in minutes has elapsed (see “
APoFF
” parameter on page 63).
Shutdown is acknowledged with a brief acoustic signal.
Exceptions:
Transmission and memory mode operation, continuous operation
and whenever a dangerous voltage is applied to the input
(U > 33 V AC or U > 70 V DC).
Automatic Shutdown – Calibrator
