• F or safety and licensing reasons, 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 devices 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 professional
trade association for electrical equipment and devices must be observed.
• In schools, training centres, hobby and self-help workshops, the operation of measuring devices must be
supervised by trained personnel.
• Before measuring voltages, always make sure that the measuring device is not set to resistance or
insulation measuring range.
• The voltage between the connection points of the measuring device and the earth potential must not
exceed 1000 V/DC or 750 V/AC in CAT III.
• When using the measuring lines without cover caps, measurements between the meter and the earth
potential must not be performed above the measuring category CAT II.
• When measuring in the measuring category CAT III, the cover caps must be pushed onto the measuring
prods to avoid accidental short circuits during measurement.
• Push the cover caps onto the measuring prods until they latch. To remove, pull the caps from the prods
with a little force.
• The test prods have to be removed from the test object before the measuring range is changed.
• Pay particular attention when dealing with voltages exceeding 33 V AC or 70 V DC! If electrical conduc-
tors are touched, even these voltages involve the risk of a fatal electric shock.
• Before measuring, always check your measuring device and its measuring lines for damage. Never carry
out measurements when the protective insulation is damaged (ripped, torn off etc.).
• The enclosed measuring cables have a wear indicator. When they are damaged, a second insulation
layer in a different colour becomes visible. The measuring accessories must no longer be used and must
be replaced.
• 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 and the
alligator clip.
• Do not use the measuring device shortly before, during or directly after an electrical storm (lightning! /
high-energy overvoltages!). Please make sure that your hands, your shoes, your clothing, the floor,
circuits and circuit components are dry.
• The measuring device must not be operated when it is open, i.e. with an open battery compartment or
when the battery compartment lid is missing.
• Measuring in potentially explosive areas (Ex) or damp rooms or under unfavourable ambient conditions
is not permitted.
• Adverse ambient conditions include:
- Dust or combustible gases, vapours or solvents
- Storms or stormy conditions, strong electrostatic fields, etc.
• A void operation near strong magnetic or electromagnetic fields, transmitter aerials or HF generators. This
might lead to distorted measuring results.
