2. Appropriate Usage

The instrument may only be used under those conditions and for those

purposes for which it was designed. For this reason, in particular the

safety references, the technical data including environmental conditions

and the usage in dry environments must be followed,

When modifying or changing the instrument, the operational safety is no

longer ensured.

The instrument may only be opened by an authorized service technician.

The voltage detectors are designed to be used by skilled persons and in

accordance with safe methods of work.
