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. outlets or sub-distribu-
tion). This category also covers all smaller categories (e.g. CAT II for measuring electronic
devices).
Ground potential
The unauthorised conversion and/or modification of the unit is inadmissible because of safety and
approval reasons (CE).
Consult an expert when in doubt about the operation, the safety or the connection of the device.
Measuring instruments and accessories are not toys and have no place in the hands of children.
On industrial sites the accident prevention regulations of the association of the industrial workers’
society for electrical equipment and utilities must be followed.
In schools, training centres, computer and self-help workshops, handling of measuring instruments must
be supervised by trained personnel in a responsible manner.
The voltage between the measuring instrument connection points and earth must never exceed 250 V
DC/AC in CAT III.
The test prods have to be removed from the measured object every time the measuring range is
changed.
Be especially careful when dealing with voltages higher than 25V AC or 35 V DC. Even at such voltages
you can receive a life-threatening electric shock when you come into contact with electric wires.
Check the measuring device and its measuring lines for damage before each measurement. Never car-
ry out any measurements if the protecting insulation is defective (torn, ripped off etc.)
To avoid an electric shock, make sure not to touch the connections/measuring points to be measured
neither directly nor indirectly during measurement. During measuring, do not grip beyond the tangible
grip range markings present on the test prods.
Do not use the multimeter just before, during or just after an electrical storm (electrical shock / high-ener-
gy overvoltage!). Please make sure that your hands, your shoes, your clothing, the floor, switches and
switching components are dry.
