The voltage between the multimeter connection points and earth must never
exceed 600 V DC/AC in CAT III.
Exercise particular caution when dealing with voltages higher than AC 30Vr.m.s,
42.4Vpeak or DC 60V. Touching electrical conductors with these voltages may
cause a fatal electric shock.
To prevent an electric shock, do not touch the measuring points when taking
measurements, either directly or indirectly. When taking measurements, do not
touch any area beyond the grip markings on the test probes / test leads.
Check the measuring device and test leads for signs of damage before each
measurement. Never take measurements if the protective insulation is dam-
aged (torn, missing, etc.). The test leads come with a wear indicator. A second
layer of insulation 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 immediately prior to, during or just after a storm (risk
of electric shock / power surge). 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
Do not switch the device on immediately after it has been brought from a cold
room into a warm one. The condensation generated may destroy the product.
Leave the device switched off and allow it to reach room temperature.
