This product has been CE-tested and meets the necessary European guidelines.
Class 2 insulation (double or reinforced insulation)
CAT II Overvoltage category II for measurements on electric and electronic devices connected
to the mains supply with a power plug. This category also covers all smaller categories
(e.g. CAT I for measuring signal and control voltages).
CAT III Overvoltage category III for measuring in building installation (e.g. sockets or sub-distribu-
tion). This category also covers all smaller categories (e.g. CAT II for measuring electronic
devices).
Earth potential
For safety and licensing reasons (CE), unauthorised conversion and/or modification of the device is not
permitted.
Consult a specialist 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 associations for electrical systems and operat-
ing 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.
Before measuring any voltages, always make sure that the meter is not set to a measuring range for
resistance or earth measurements.
The voltage between the measuring instrument connection points and earth potential must never exceed
600 V DC/AC in CAT III. The voltage between the "P" and "E" connection points must never exceed
200 V/AC.
The test probes have to be removed from the measured object every time the measuring range is
changed.
Take particular care when dealing with voltages exceeding 25 V AC or 35 V DC! Even at these voltages
it is possible to get a fatal electric shock if you touch electrical conductors.
Prior to each measurement check your meter and its measuring lines for any damage. Never carry out
measurements when the protective insulation is damaged (ripped, torn off etc.).
In order to avoid an electric shock, ensure that you do not touch the connections to be measured, even
indirectly, during measurements. During measuring, do not grip beyond the tangible grip range markings
present on the test probes and alligator clamps.
Do not use the meter immediately prior to, during or just after an electrical storm (electrical shock risk! /
high-energy overvoltages!). Please make sure that your hands, your shoes, your clothing, the floor,
switches and switching components are dry.
