72 h operation
(operation without permanent supervision)
If the instrument should run for a longer period of time without super-
vision (e.g. at the weekend), use this function to check whether suffi-
cient indicator is available for a continuous measurement.
On the basis of the still available indicator, the set indicator pause
and indicator quantity consumed per measurement, the instrument
calculates whether the residual indicator quantity is sufficient for the
next 72 operating hours.
Press key 3 (standby) for approx. 2 seconds to check whether 72 h
operation is possible.

The LED above key 3 (standby)

not. Further steps as described below.
If several consecutive faulty measurements have occurred, the
LED “POWER” lights and the LED above key 4 (horn) is blinking.
