2. Safety instructions
The instrument is built and tested in accordance with
DIN VDE 0411 Teil 1/ EN 61010-1
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.
The device must be used in electrical circuits of overvoltage
category II with a conductor for a maximum of 1000 V to earth
or of overvoltage category III with a conductor for a maximum
of 600 V to earth only.
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.
Please observe that work on live parts and electrical compon‑
ents 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 current clamp multimeter, always check the

device as well as all measuring leads for damages.
If it can be assumed that safe operation is no longer possible, switch the device
off immediately and secure it against unintended operation.
Safe operation can be assumed to be no longer possible, if
- the device or the measuring leads exhibit visible damages,
- the device no longer works,
- the device has been stored under unfavourable conditions for a longer pe-
riod of time,
- the device was exposed to extraordinary stress during transport.
In order to prevent danger
- d o not touch the bare measuring probe tips of the measu‑

ring leads,
- i nsert the measuring leads into the respectively designated
measuring sockets of the multimeter.
