Do not operate the measuring device unsupervised or only
protected against unauthorized access.
Use the multimeter only for the purpose of its determination
and pay particular attention to warning notices on the device
and information on the maximum input values.
Electric safety:
Voltages over 25 VAC or 60 VDC are generally considered
dangerous voltages.
Only work on dangerous voltages by or under the
supervision of qualified personnel.
When working on dangerous voltages, wear suitable
protective equipment and observe the relevant safety rules.
Do not exceed the maximum permissible input values under
any circumstances (risk of serious injury and / or destruction
of the device)
Pay special attention to the correct connection of the test
leads depending on the measuring function in order to avoid
a short circuit in the device. Never apply a voltage in parallel
to the current sockets (A, mA, µA).
Current measurements are always carried out in series with
the consumer, i.e. with the supply line disconnected.
Remove the test probes from the measurement object before
changing the measuring function.
Never touch the bare test probes during the measurement,
only hold the test leads by the handle behind the finger
guard. If applicable, discharge any capacitors before
measuring the circuit to be measured.
Measurement environment:
Avoid any proximity to explosive and flammable substances,
gases and dust. An electric spark could lead to an explosion
or deflagration - danger to life!
Do not carry out measurements in corrosive environments,
the device could be damaged or contact points inside and
outside the device could corrode.
Avoid working in environments with high interference
frequencies, high-energy circuits or strong magnetic fields,
as these can negatively affect the multimeter.
