3.2 Operation
30mA Auto Test
The 30mA auto test is available for A and AC type RCD. Select the required
30mA auto test on the rotary dial. The tester will monitor the mains for
correct polarity and voltage. If parameters are correct the Volts Present
LED will illuminate green and a test can the carried out. On pressing the
test button. The auto test will begin. X½ , x1 and x5 tests will
automatically be carried out at 0º and 180º. The results can be seen by
using the recall button to toggle through results.
RCD Manual Testing
Select the required RCD type on the rotary dial. Then use the multiplier
button to select the required test current. If the mains polarity and
voltage is correct the volts present LED will illuminate green and a test can
be carried out by pushing the test button. The first test will always be
done at 0°. The tester will then automatically cycle to 180° ready for the
next test.
Ramp Test
Rather than applying a set test current, this gradually increases the level
of additional leakage to identify at what current the RCD trips. Select the
required RCD type on the rotary dial. Then use the multiplier button to
select the ramp feature. If the mains polarity and voltage is correct the
