Protection Class 2 symbol (double insulation)
• Measuring devices should be kept away from children!
• In the workplace, the accident prevention measures of the
Association of Employer's Liability Insurance for electrical
plant and operating material must be observed.
• In schools, training centers, hobby and self-help workshops,
measuring equipment and accessories must be responsibly
supervised by trained personnel.
• When opening panels or removing parts (except if this is
manually possible), live components may be exposed.
Connecting points may also be live. Ahead of any adjust-
ment, maintenance, repair or exchange of parts or sub-
assemblies during which the unit must be opened, connec-
ting points must be disconnected from all voltage sources
and measurement circuits. If adjustment, maintenance or
repair must then proceed with the unit open, only trained
engineers, familiar with the risks and relevant regulations
(VDE-0100 or VDE 0701 and VDE 0686) are authorized to
complete the work.
• Capacitors in the unit may still be charged, even when the
unit has been disconnected from all power sources and mea-
suring circuits.
• Please take special care when handling voltages in excess of
25 V AC or 35 V DC voltage. Even at these voltages, contact
with electric cables can give a potentially lethal electrical
shock.
Therefore, start by switching the voltage source to no-load,
connect the measuring device to the terminals of the voltage
4
source you are measuring, set the measuring device to the vol-
tage measuring range required and then switch on the voltage
source. On completion of the measurement, switch the voltage
source to no-load and remove the measurement cables from
the terminals of the voltage source.
• Ahead of any voltage measurement, check that the measu-
ring device is not in the current measuring range.
• Ahead of modifying the measuring range, always remove the
clamp-on ammeter from the measurement object (conductor
rail, cable, etc.).
• For measuring other parameters than current (such as voltages,
resistances, frequencies, etc.) use only the measuring cables
supplied with the measuring device. Only these are applicable.
• Ahead of measurements, always check your measuring device/
measuring cable en for damage. Never make measurements if
the protective insulation is damaged (split, broken, etc.).
• Do not use the measuring device in rooms or in adverse envi-
ronmental conditions in which combustible gases, vapors or
dust are present or may be present.
For your own safety, ensure that neither the measuring device
nor measuring lines do not become damp or wet.
Avoid excess humidity and vapor. When measuring, it is abso-
lutely necessary that your hands, shoes and the floor are dry.
• To avoid electric shocks, check that there is no contact (not
even indirectly) with measurement probes and the termi-
nals/conductor rails (measurement point) during the measu-
rements.
Measurements of current sources with inductive/capacitive
loads and measurements during thunderstorms are extremely
dangerous (because of the very high voltages/discharges
which may occur) and should thus be avoided.
Currents > 600 A result in damage to the clamp-on ammeter.
