Safety note

The instrument is built and tested in accordance with
DIN VDE 0411 part 1/ EN 61010-1
DIN VDE 0411 part 2-032/ EN 61010-2-032
DIN VDE 0411 part 031/ EN 61010-031
and has left the factory in perfectly safe technical condition.
To maintain this condition and to ensure safe operation of the unit, the user must observe
the notes and warnings given in these instructions at all times. Improper handling and non-
observance of the warnings might involve severe injuries or danger to life.

WARNING! Be extremely careful when working with bare conductors or main
line carrier! Contact with live conductors will cause an electric shock!
The unit may be used only in power circuits within the overvoltage category III
and IV with a conductor for 300 V max. to earth.
Only use suitable measuring leads for this. With measurements within
measurement category III and IV, the projecting conductive part of a contact

tip of the measuring leads must not be longer than 4 mm. Prior to carrying
out measurements within measurement cat egory III and IV, the push-on caps
provided with the set and marked with CAT III and CAT IV must be pushed onto
the contact tips. The purpose of this measure is user protection.
Remember that work on electrical components of all kinds is dangerous. Even
low voltages of 30 V AC and 60 V DC may be dangerous to human life.

Before starting the unit, always check it as well as all measuring lead and wires
for signs of damage.
Should it appear that safe operation of the unit is no longer possible, it should be shut down
immediately and secured to prevent that it is switched on accidentally.
It may be assumed that safe operation is no longer possible:
- if the device or the measuring lead exhibit visible damages,
- if the unit no longer works,
- after long periods of storage under unfavourable conditions,
- after being subject to rough transportation, or
- if the device or the measuring lead are exposed to moisture.
