VOLTCRAFT VC-530 Bedienungsanleitung Seite 33

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 measur-
ing instruments must be supervised by trained personnel in a responsible manner.
The voltage between the connecting points of the measuring device and earth must
never exceed 600 V DC/AC in CAT III.
The test prods have to be removed from the measured object every time the mea-
suring range is changed.
Take particular care when dealing with voltages exceeding 25V AC or 35V DC! Even
at these voltages it is possible to get a fatal electric shock if you touch electric conduc-
tors.
Check the measuring device and its measuring lines for damage before each mea-
surement. Never carry out any measurements if the protecting insulation is defec-
tive (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 and on the on-clamp ammeter sensor.
Do not use the measuring device just before, during or just after an electrical storm
(electrical shock / high-energy overvoltages!). Please make sure that your hands,
your shoes, your clothing, the floor, switches and switching components are dry.
Avoid an operation near:
- strong magnetic or electromagnetic fields
- transmitter aerials or HF generators,
Since this could affect the measurement.
