POWERFIX PDM 300 B1
If smoke is produced, or there are any unusual sounds or smells, stop measuring immediately. In
these cases, the multimeter should not be used until it has been inspected by authorised service
personnel. Never inhale smoke from a potential device fire. If you have inhaled smoke, however,
consult a doctor. The inhalation of smoke can be harmful.
The test probes may be handled only behind the finger protection as otherwise there is a risk of
an electric shock when measuring!
If the multimeter or the test probes are damaged (including test lead), they must not be used.
There is a risk of an electric shock!
Pay particular attention to your safety when dealing with AC voltages over 30V or DC voltages
over 60V. There is a risk of an electric shock!
Never operate the multimeter when the housing is open. There is a risk of an electric shock!
Ensure that you do not touch the test probes and the jacks to be measured during a
measurement in order to avoid an electric shock.
Do not use the multimeter in wet or damp environments. Also ensure that your hands and shoes
are dry as there is a risk of an electric shock otherwise!
Do not use the multimeter in the vicinity of explosive gases or vapours or in a dusty environment.
It poses a risk of explosion!
Ensure that no fire sources (e.g. burning candles) are placed on or near the multimeter. It poses
a fire hazard!
Do not exceed the maximum specified input values for the individual measuring ranges.
Otherwise, the multimeter could be damaged.
Do not exceed the specified overvoltage category CAT III. Otherwise, the multimeter could be
damaged.
CAT III: Measurements within the building installation (e.g. distributors, wiring, sockets and
switches). This category also includes the following two categories: CAT II: Measurements on
electrical and electronic devices that are supplied with a voltage via a mains plug.
CAT I: Measurements on circuits that have no direct connection to the mains power supply
(battery operated, motor vehicle electrics, etc.).
The multimeter must be disconnected from the test object before changing the measuring range
as the multimeter could be damaged otherwise.
When working with the test probes, first connect the black test lead to the COM jack before you
connect the red test lead. When disconnecting the test probes, first remove the red test probe.
Never connect a voltage source to the test probes if the areas continuity test, resistance
measurement, diode test, function generator or current measurement are selected. Otherwise, the
multimeter could be damaged.
