VOLTCRAFT VC292 Bedienungsanleitung Seite 64

Always remove the measuring probes from the measured object before chang-
ing the measurement range.
The voltage between the multimeter connection points and earth must never
exceed 600 V DC/AC in CAT III.
Exercise particular caution when working with voltages higher than AC
30 Vr.m.s, 42.4 V peak or DC 60 V. Touching electrical conductors with these
voltages may cause a fatal electric shock.
To prevent an electric shock, do not touch the connections/measuring points
when taking measurements, either directly or indirectly. When taking measure-
ments, do not touch any exposed areas beyond the grip markings on the meas-
uring probes and the clamp transformer.
Check the multimeter and test leads for signs of damage before each measure-
ment. Never take measurements if the protective insulation is damaged (torn,
missing, etc.). The test leads come with a wear indicator. A second layer of insu-
lation will become visible if the lead is damaged (the second layer of insulation is
a different colour). If this occurs, discontinue use and replace the measurement
accessory.
Do not use the multimeter just before, during or just after an electrical storm
(electric shock /high-power surges!). Ensure that your hands, shoes, clothes,
the floor, circuit and circuit components are dry.
Avoid using the device in the immediate vicinity of:
– Strong magnetic or electromagnetic fields
– Transmitting antennas or HF generators.
These may distort the measurements.
If you suspect that safe operation is no longer possible, discontinue use im-
mediately and prevent unauthorized use. Safe operation can no longer be as-
sumed if:
– There are signs of damage
– The device does not function properly
– The device was stored under unfavourable conditions for a long period of
time
– The device was subjected to rough handling during transport
