Safety notes
The instrument is built and tested in accordance with
DIN VDE 0411 part 1/EN 61010-1
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 maintain this condition and to ensure safe operation of the multimeter, 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 BENNING MM 5-1/ MM 5-2 may be used only in electrical
circuits of over voltage category III with a maximum voltage of
600 V or of over voltage category IV with a maximum voltage of
300 V between the conductor and ground.
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 cat-
egory 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.
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 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 subject to rough transportation, or
-
if the device or the measuring leads are exposed to moisture, or
In order to avoid danger,
-
do not touch the bare probe tips of the measuring leads
measuring leads,
-
insert the measurement leads in the appropriately
designated measuring sockets on the multimeter
Cleaning:
Regularly wipe the housing by means of a dry cloth and
cleaning agent. Do not use any polishing agents or solvents!
