Figure 5.3.1 Instrument ready for operation
Connect the desired test leads to the UUT. Please
refer to Figure 5.3.2 or Figure 5.3.3 for connec-
tion.

If the test instrument shows the pin assign-
ment in compliance with Figure 5.4.5, i.e. the
'turn mains plug' symbol (5) is flashing, the
test cannot be started. When starting the test,
an acoustic signal is audible. The shockproof
plug must be turned or L and N have to be ex-
changed for the test leads connected.
To carry out the socket test touch the contact
electrode 'PE' (21).
If the test instrument indicates the symbols
(14), 'socket error' (4), and 'PE error' (16), or
'contact voltage' (15), in compliance with fig-
ure 5.3.6, the protective conductor (PE) is open
or a voltage is present! This error is fatal and
must immediately be eliminated!
