Step 1
Instrument displays the message »
Press START key for new test.
«.
After setting the parameters, press the START key to apply a voltage to the main
test socket.
Step 2
The instrument displays the message »
RCD ON and press START key to
proceed.
«.
Check that the RCD is switched ON (most of portable RCDs must be manually
switched on after they plugged in) and the PRCD test probe is connected
properly between the PRCD socket of the instrument and the mains connections
of the RCD (as illustrated in chapter
6.8.1 RCD test on appliance
).
The conditions for performing the test are fulfilled when the displayed voltage
indication shows that a voltage is applied.
The autotest sequence starts to run as described in the following steps.
Step 3
Trip-out time measurement with the following measurement parameters:
Ì
test current of I
Δ
N
,
Ì
test current started with the positive half-wave (from 0
0
).
The measurement normally trips an RCD within the allowed time period. The
following menu is displayed:

After resetting the RCD, the autotest sequence automatically proceeds with the
next step.
Step 4
Trip-out time measurement with the following measurement parameters:
Ì
test current of 5
×
