Multifunction Tester
Applications

Preset 2 includes multiple live tests:
Line test (L-N)
NoTrip Loop test (L-PE)
RCD test:
Ramp test (type A or type AC, 30 mA, 100 mA, 300 mA)
or
Auto RCD test (type A or type AC, 30 mA, 100 mA)
Preset 3 includes multiple dead tests:
Insulation tests:
L-PE, 50 V to 1000 V
L-N, 50 V to 1000 V
N-PE, 50 V to 100 V
Continuity
L-PE
L-N
N-PE
The Tester starts with the Line/Loop test, then it tests the RCD. After the RCD has tripped, it
proceeds with insulation tests. The insulation Safety Pretest and the Zmax are always active.
This test sequence is intended to be done at a mains socket with the mains test cord at circuits
that are protected by an RCD with a nominal fault current of ≥30 mA.
Note
The automatic test sequence will trip an RCD. Because an insulation test is part of the
sequence, make sure that no appliances are connected to the circuit under test.
If the L and N terminals are reversed, the Tester will auto-swap them internally and
continue the tests. If the Tester is configured in L-N mode (no auto lead swap), tests
are stopped. Icons indicate if L-PE or L-N terminals are reversed.
