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!
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, 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 any socket of the measuring instrument and the ground may not be higher than
500 V DC/AC in excess voltage category III.
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.
Prior to each measurement, check your instrument including its measuring lines for damage. Never car-
ry 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. 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 over-
voltages!). Ensure that your hands, shoes, clothing, the floor, the measuring instrument, the measuring
lines, switches and switching parts, etc. are dry.
Do not operate the measuring instrument in surroundings or unfavourable conditions where combustible
gases, vapours or dust are or may be present.
Avoid operation in the immediate vicinity of:
- strong magnetic or electromagnetic fields
- transmitting aerials or HF generators.
This might lead to distorted measuring results.
For safety reasons, only use measuring lines or accessories in correspondence with the specifications of
the multimeter. Only measuring equipment with double or reinforced insulation may be used (e.g. fully
insulated BNC adapters, etc.)
