• The voltage between the connection points of the measuring device and earth
potential must not exceed 600 V (DC/AC) in CAT III.
• When using test leads without protective caps,
measurements between the measuring device
and the earth potential must not exceed the CAT II
measurement category.
• When taking CAT III measurements, the protective
caps must be placed on the probe tips to avoid ac-
cidental short circuits.
• Push the protective caps onto the probe tips until
they click into place. To remove the caps, pull them
off the tips with some force.
• Always remove the probe tips from the measured object before changing the
measurement range.
• Exercise particular caution when working with voltages higher than 33 V (AC)
and 70 V (DC). Touching electrical conductors with these voltages may cause a
fatal electric shock.
• Check the measuring device and test leads for signs of damage before each
measurement. Never take measurements if the protective insulation is damaged
(torn, missing, etc.).
• Measuring cables have a wear indicator. The second layer of insulation will be-
come 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.
• 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 probe tips.
• Do not use the multimeter just before, during or just after an electrical storm (elec-
tric 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.
