2. Safety note
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 maintain this condition and ensure safe operation of the multimeter, the user
must observe the notes and warnings given in these instructions at all times.
The unit may be used only in power circuits within the overvolt-
age category III with a conductor for 600 V max. 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 cat-
egory 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.

Before starting the multimeter up, always check it as well as all
cables 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 it being 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 functions, or
- after long periods of storage under unfavourable conditions, or
- after being subjected to rough transport.
In order to avoid danger,

- do not touch the bare prod tips of the measuring leads,
- insert the measurement leads in the appropriately
designated measuring sockets on the multimeter
