This test measures the RCD tripping current by applying a
test current and then gradually increasing the current until
the RCD trips. You can use the test leads or mains cord
for this test. A 3-wire connection is required.

•
Test the connection between the N-
conductor and earth before starting the
test. A voltage between the N-conductor
and earth may influence the test.
•
Leakage currents in the circuit following
the residual current protection device
I
N
may influence measurements.
•
The displayed fault voltage relates to the
residual operating current of the RCD.
•
Potential fields of other earthing
installations may influence the
apx009f.eps
measurement.
If the L and N terminals are reversed, the tester
will auto-swap them internally and continue
testing. If the tester is configured for UK
operation, testing will halt and you will need to
manually swap the terminals. This condition is
indicated by arrows above or below the terminal
indicator symbol ( b ). See Power-On Options
on page 18 for information on setting Line and
Neutral Swap mode.
