Step 2 Set the following measuring parameters:
• I : Nominal differential trip-out current
ΔN
Factor: Nominal differential trip-out current multiplier
•
• Type: RCD type
• Pol.: Test current starting polarity
Step 3 Connect the leads to the instrument and follow the connection diagram shown in figure
4.12 (see the chapter 4.3.1 Contact voltage) to perform trip-out time measurement.
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. After performing the measurement, the results appear on the display TEST key. After performing the measurement, the results appear on the display
together with the

Notes:
• Parameters set in this function are also transferred onto all other RCD functions!
• RCD trip-out time measurement will be performed only if the contact voltage at nominal
differential current is lower than the limit set in the contact voltage setting!
• The measurement of the contact voltage in 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
or indication.
