CAT IV Overvoltage category IV for measuring at the source of low-voltage installations (e.g.
main distributor, transfer point of energy provider in buildings). This category also
covers all smaller categories (e.g. CAT III).
Earth potential
For safety and licensing reasons (CE), unauthorised conversion and/or modification of the device is
not permitted.
Consult an expert when in doubt as to the operation, the safety or the connection of the device.
Measuring instruments and accessories are no toys and do not belong in the hands of children!
In commercial facilities the regulations for the prevention of accidents as laid down by the profession-
al trade association for electrical equipment and devices must be observed.
In schools, training centres, hobby and self-help workshops, the operation of measuring instruments
must be supervised by trained personnel.
Before measuring voltages, always make sure that the measuring instrument is not set to current
range.
The voltage between the connecting points of the measuring instrument and the earth potential must
not exceed 600 V DC/AC in CAT IV.
The test prods have to be removed from the test object before the measuring range is changed.
Take particular care when dealing with voltages exceeding 25 V AC or 35 V DC! If electrical conductors
are touched, even these voltages involve the risk of a fatal electric shock.
Before measuring, always check your measuring instrument and its measuring lines for damage. Never
carry out measurements when the protective insulation is damaged (ripped, torn off etc.).
To avoid an electric shock, do not to touch the connections/measuring points directly or indirectly during
measurements. When measuring, only touch within the tangible grip markings on the test prods.
Do not use the multimeter shortly before, during or just after a thunderstorm (lightning!/high-energy
overvoltages!). Please make sure that your hands, your shoes, your clothing, the floor, circuits and cir-
cuit components are dry.
Avoid operation near strong magnetic or electromagnetic fields, transmitting aerials or HF generators.
This might lead to distorted measuring results.
If you have reason to believe that the device can no longer be operated safely, disconnect it immedi-
ately and make sure it is not unintentionally operated. It can be assumed that safe operation is no
longer possible if:
