The test current can be selected by pressing the F4 key. Repeat press
the F4 key until the desired RCD test current is displayed.
TEST
When the required settings have been selected, press the TEST key to
begin the sequence. The test sequence will perform the following tests at
set test current;

The Trip Time is shown in the primary display.
During the sequence if any test passes and does not trip the RCD then
the DL9120 / DL9130EV will move on to the following test.
If any test passes and does trip the RCD then the DL9120 / DL9130EV
will move onto the following test as soon as the RCD has been reset.
If any test fails then the sequence is aborted.

Once the test sequence is complete the results from the test sequence
can be reviewed using F3 (Recall).
5.10 Auto EV Test Sequence (DL9130EV only)
The DL9130EV will only allow the RCD test to be performed
if the correct voltages are detected between line-earth (L-
PE illuminated), line-neutral (L-N illuminated) and neutral-
earth (N-PE
not
illuminated).
Potential fields from other earthing installations, large
voltages between the protective conductor and earth, large
voltage between the neutral and earth or leakage currents
in the circuit following the residual current protection device
may influence the measurement.
