Contact voltage
t Trip-out time
Notes:
• Parameters set in this function are also kept for other RCD functions!
• RCD trip-out current measurement will be performed only if the contact voltage at nominal
differential current is lower than set limit contact voltage!
• The measurement of contact voltage in the pre-test does not normally trip an RCD. However,
the trip limit may be exceeded as a result of leakage current flowing through the PE protective
conductor or a capacitive connection between L and PE conductors.

4.3.4 Autotest

How to perform RCD autotest
Step 1 Select the RCD function FCT key and select the Auto mode with the ▲▼ and ◀▶
navigation keys. The following menu will be displayed:
Step 2
Set the following measuring parameters:
• I : Nominal differential trip-out current
ΔN
• Tipo: RCD type
Step 3 Connect the test leads to the instrument and follow the connection diagram shown in
figure 4.12 (also see the chapter 4.3.1 Contact voltage) to perform the RCD autotest.
Step 4
Check for any warnings and check the online voltage/terminal monitor on the display
before starting the measurement. If everything is ok and the
TEST key. The autotest sequence will then start to run as follows:
1. Trip-out time measurement a test current of IΔN, started with the positive half-wave at
0º. Measurement normally trips an RCD within allowed time period.
