For safety and licensing reasons (CE), unauthorised conversion
and/or modification of the device is not permitted.
Consult suitably qualified staff, if you have doubts about how the
appliance operates or about how to connect it safely.
Measuring instruments and accessories are not toys and have no
place in the hands of children.
The accident prevention regulations of the relevant trade associa-
tions for electrical systems and operating materials are to be
observed in commercial institutions.
In schools, training centres, computer and self-help workshops,
handling of measuring instruments must be supervised by trained
personnel in a responsible manner.
Always make sure before measuring voltages that the measuring
instrument is not set to a current measuring range.
The voltage between the two measuring device and the ground
potential must not exceed 600 V DC/AC in overvoltage category IV.
Measurements between measuring instrument and ground potential
are not tob e carried out above overvoltage category CAT II when
using the measuring leads without cover caps. When measuring in
the measurement categories CAT III and CAT IV the cover plugs
must be on the test prods in order to avoid unintentional short cir-
cuits during the measuring operation.
Push the cover plugs onto the test prods until these lock on. To
remove them pull the covers with some force from the prods.
Before changing the measuring range, the test prods have to be
removed from the measured object.
