Power saving circuit The device is switched off automatically:
– If the measured value remains
unchanged for a period of approximately
10 minutes, and if none of the controls
are activated during this time.
Automatic shutdown can be deactivated.
– If battery voltage drops to below
approx. 1.8 V

– A slow-blow fuse is additionally
connected in series to the auto-fuse, the
blowing or absence of which is detected
automatically (display “FUSE”):
