10.0 Energy Management
Approximately 5 minutes after the last key operati-
on, the instrument switches off automatically (auto-
power-off). To switch the instrument on again, turn
the rotary switch from the „OFF" position to the de-
sired function. If the Batterie is unloaded almost, the
symbol (8) appears in the indication. The piece of
equipment works furthermore, however without
claim on retention of the spezifications. If the batte-
rie will unload further, the piece of equipment swit-
ches itselfs off when reaching the minimal battery
tension. At empty battery hasn´t switched the piece
of equipment on.

(chapter 3.0),as well as the technical data including
environmental conditions (chapter 15.0) and the
usage in dry environments must be followed at all
times.
When modifying or changing the instrument,
the operational safety can no longer be gua-
ranteed.

allowed to be connected to the measurements
