Auto Test Sequence (1664 FC)
The 1664 FC includes the Auto Test feature. Auto Test allows you to start
multiple tests with one press of
:
• Line test (L-N)
• NoTrip Loop test (L-PE)
• RCD test:
o Ramp test (type A or type AC, 30 mA, 100 mA, 300 mA)
-or-
o Auto RCD test (type A or type AC, 30 mA, 100 mA)
• Insulation tests:
o L-PE, 50 V to 1000 V
o L-N, 50 V to 1000 V
o N-PE, 50 V to 1000 V
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. This
condition is indicated by arrows above the terminal indicator
symbol (b).
To start an Auto Test:
1. Turn the rotary dial to the
AUTO TEST position. See Table 19.
2. Connect the mains test cord to the Tester.
