Safety notes
The instrument is built, tested and approved in accordance with
DIN VDE 0411 part 1/ EN 61010-1
and has left the factory in perfectly safe technical state.
To maintain this state and ensure safe operation of the appliance tester, 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
overvoltage category III with a conductor for 1000 V max. to
earth, or within overvoltage category IV with a conductor for
600 V against 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
category III and measurement category IV, the pushon 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 appliance tester 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 desig-
nated measuring sockets on the multimeter
