Safety instructions

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 2-033/ EN 61010-2-033
DIN VDE 0411 Part 031/ EN 61010-031
and has left the factory in perfectly safe technical condition.
To preserve this condition and to ensure safe operation of the device, 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 con-

ductors or main line carrier! Contact with live conductors will
cause an electric shock!
The unit may be used only in electrical circuits of overvoltage
category III with a maximum voltage of 1000 V to earth, or of
overvoltage category IV with a maximum voltage of 600 V to
earth.
Only use suitable measuring leads for this. With measurements
within measurement category III, 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 ca-
tegory III, 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.
In order to prevent any danger, always measure a present vol-

tage first without low-pass filter (without high-frequency sup-
pression) to detect a dangerous voltage.
Before starting the multimeter, always check it as well as all

measuring leads and wires for signs of damage.
Should it appear that safe operation of the multimeter 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 instrument or the measuring leads show visible signs of damage, or
- if the multimeter no longer works, or
- after long periods of storage under unfavourable conditions, or
- after being subjected to rough transport, or
- if the device or the measuring leads are exposed to moisture.
In order to avoid danger,
- do not touch the bare probe tips of the measuring leads,

- insert the measurement leads in the appropriately desig-
nated measuring sockets on the digital current clamp multi-
meter
Cleaning:

Regularly wipe the housing by means of a dry cloth and clea-
ning agent. Do not use any polishing agents or solvents!
