Step 2
By using cursor keys the following parameters can be set in this
measurement:
•
I
ΔN
: Nominal residual current,
•
Type:
RCD type,
•
Pol.:
Test current starting polarity.
Step 3
Connect the test leads to the instrument and follow the connection diagram shown in
figure 5.15 (see the chapter
5.3.6 Contact voltage
) to perform trip- out current
measurements.
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
is shown,
press the TEST key. After performing the measurement, the results appear on the
display together with the
or
indication.
