
If the operator’s safety is no longer guaranteed, the instrument is to be put out
of service and protected against use. The safety can no longer be guaranteed if
the instrument (or test leads):
– shows obvious damage
– does not carry out the desired measurements
– has been stored for too long under unfavourable conditions
– has been subjected to mechanical stress during transport.

Dangerous voltages may be present on appliances/devices under test (DUT)
caused by defective insulation. Do not touch the appliance/device under test,
danger of electrical shock!

Start any test series by visual inspection and protective earth bond resistance
measurement.

For protective earth bond resistance test, insulation test and substitute leakage
test, appliance/device under test must be voltage-free (mains supply). If
necessary, check the appliance/device if it is voltage-free i.e. by using a two
pole tester acc. to IEC/EN 61243-3.

Accidental measurement of a defective appliance/device may trip an RCD
(residual current device) of supply.

During the earth leakage current test, the touch leakage current test and the
function (load) test, the DUT will be energized at mains voltage. DUT driven by
motors or equipped with heating elements may present a danger for the
person testing or others (Comply with the user’s manual of the DUT!). Please
ensure that the DUT is in a safe condition to run and secure prior to testing.
Appropriate Usage
WARNING

The instrument may only be used under conditions and for the purposes for
which it was conceived. For this reason, and particular the safety references,
the technical data including environmental conditions and the usage in dry
environments must be followed.

When modifying the instrument, the operational safety is no longer ensured.

The instrument may only be open by an authorised service technician. Before
opening the instrument must be switched off and disconnected from any
electrical circuit.
