3. Functional test
- Check the phase indicator and cable break detector for correct functioning immediately before and
after using it!
- Test the phase test for correct functioning with a familiar voltage source, e.g. a 230 V socket/5-pin
CEE socket.
- Please replace the batteries as soon as the red LED indication
weaker.
- Do not use the BENNING VT 1, if not all functions are working properly!
- The BENNING VT 1 has no circuit breaker and is always enabled. A special circuit with low current
consumption extends the battery lifetime and thus ensures that the device is ready for use.
4. Howtheindicatorworks
- The BENNING VT 1 phase indicator and cable break detector detects electric fields generated by
phase/external conductor voltages from 200 V to 1,000 V AC (45 Hz to 65 Hz) on.
- If an electric field is detected, the probe tip
ted. The flashing frequency of the red probe tip
increase with the electric field or the voltage applied increasing as well.
- The BENNING VT 1 phase indicator and cable break detector can be used to determine the phase
(external conductor) of an AC voltage.
- The test does not require any current flow and no electrically conductive contact with the system
part, socket or insulated line.
- Please observe that the BENNING VT 1 only responds to sufficiently strong fields with a phase/
external conductor voltage from 200 V AC on.
If the BENNING VT 1 phase indicator and cable break detector does not react, the distance to the live
system part might be too large, the system part might be shielded or the insulation might be too thick.

Attention!
Please observe that even if the BENNING VT 1 does not indicate a phase (external conductor), a dan-
gerous voltage may be applied to the test object nevertheless. For determining the absence of voltage,
only use a two-pole voltage tester complying with the DIN EN 61243-3 (VDE 0682-401) standard, e.g.
a DUSPOL voltage tester.
