Benning TRITEST easy Operating Manual page 8

- Test the phase/phase sequence tester for correct functioning with a famil-
iar voltage source, e.g. a 230 V socket/5-pin CEE socket.
- Replace the batteries, if the tester switches off directly after being switched
on or if the LEDs
- Do not use the TRITEST
The TRITEST
(APO, Auto-Power-Off). An acoustic signal confirms that the tester has
switched off. Alternatively, press and hold the blue push-button
switch the TRITEST
4. How the tester works
- The TRITEST
generated by phase/external conductor voltages from 200 V to 1,000 V AC
(45 to 65 Hz) on.
- If an electric field is detected, the probe tip
acoustic signal is emitted. The flashing frequency of the red probe tip
well as the frequency of the acoustic signal increase with the electric field
or the voltage applied increasing as well.
- The TRITEST
mine the phase (external conductor) of an AC voltage as well as the phase
sequence of a three-phase mains.
- 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 TRITEST
strong fields with a phase/external conductor voltage from 200 V AC on.
If the TRITEST
tance to the live system part might be too large, the system part might be
shielded or the insulation might be too thick.
5. Phase/external conductor test of an AC voltage (figure B)
- Press and hold the blue push-button
- The yellow LED
- Place the probe tip
system part.
- If the phase (external conductor) has been detected, this is confirmed by
an acoustic signal and by the probe tip
Attention!
Please observe that even if the TRITEST
ternal conductor), a dangerous voltage may be applied to the test object. For
determining the absence of voltage, only use a two-pole voltage tester com-
plying with the DIN EN 61243-3 (VDE 0682-401) standard, e.g. a DUSPOL
voltage tester.
Note on testing insulated lines (figure C):
To localize interruptions of live lines (e.g. a cable break in a cable reel or defec-
tive lamps in a chain of lights), pass the probe tip
from the feeding point (phase) in direction of the other end of the line.
For testing a cable reel, make sure to turn the shock-proof plug by 180° in order
to connect both lines to the phase (external conductor) of a shock-proof socket.
