(P)RCD autotest function is intended to perform a complete (P)RCD analysis (trip-out
times at different residual currents and starting polarity phases) .
(P)RCD autotest procedure
(P)RCD Autotest steps
Notes
Select the RCD (PRCD) test function.
Set AUTO mode.
Select
test
parameters.
PRCD:
Connect tested PRCD / device to an external
voltage socket. Connect the IEC cord to the
instrument´s MAINS terminal and PRCD (see
Figure
5.36b
). Or connect tested PRCD between test
socket and IEC connector of the DeltaGT Connect
the instrument to mains voltage (see
Figure 5.36c
).
Depending on the type of PRCD, it may be
necessary to manually switch it on.
RCD:
Connect the DeltaGT MAINS terminal to mains
socket protected by tested RCD (see
Figure 5.36a
).

Notes:
Consider any displayed warning before starting measurement! The
symbol
means that the polarity of the mains cord should be changed.
Mains voltage is applied to the (P)RCD under test. Do not touch the equipment
under test or the test cord during the test.

Power test
The DUT’s power consumption is measured in this test. The apparent power is a useful
indication of proper operation of the appliance.
