2. Safety instructions
The instrument is built and tested in accordance with
DIN VDE 0411 Part 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 BENNING CM 1-3 must be used in electrical circuits of
overvoltage category III with a conductor for a maximum of
1000 V to earth or of overvoltage category IV 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 or measurement category 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
category III and measurement category 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.
Please observe that work on live parts and electrical compo-
nents 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
period of time,
- the device was exposed to extraordinary stress during transport.
In order to prevent danger
- do not touch the bare measuring probe tips of the mea-
suring leads,
- insert the measuring leads into the respectively designated
measuring socket of the multimeter.
