After re-activating the RCD, the autotest sequence automatically proceeds
with step 2.
2. Trip-out time measurement with the following measurement parameters:
 Test current of I
N
,
 Test current started with the negative half-wave at 180
0
.
Measurement normally trips an RCD. The following menu is displayed:

After re-activating the RCD, the autotest sequence automatically proceeds
with step 3.
3. Trip-out time measurement with the following measurement parameters:
 Test current of 5I
N
,
 Test current started with the positive half-wave at 0
