Phase Test
The phase conductor is identified by establishing
contact between the test electrode marked with +L1
and the conductor and by touching the accessible
electrode „Pol-L1-Sensor“ at the same time. When
the conductor is energized, a triangle appears in the
LCD indicator and lights up.
Note!
If the other test probe (w L1) is used during
single-pole tests and voltage is applied, the V sym-
bol appears on the LCD in addition to the triangle.
Depending on the location (insulated ground), the
Ω-symbol may be indicated as well. The symbols
additionally indicated are meaningless in this case.
Phase sequence test
To determine the phase sequence between two
phases in the 230/400 V 3-phase network by apply-
ing both test electrodes and touching the accessible
electrode, proceed as follows:
Search for the phase conductors using one pole (see
phase test).
Apply both test electrodes to two phase conductors
(display while pressing switching probes: approx.
400 V). Touch the accessible electrode with your
finger. When phase L1 is applied to the test prod
L1, and phase L2 to the other test prod,
the triangle lights up if rotation is clockwise. If the
triangle does not light up, the direction of rotation is
counter-clockwise.
Note!
If 230 V is displayed instead of 400 V (while pressing
switching probe), the neutral conductor may have
been contacted with one of the test prods.
A simple way of checking is by exchanging the
two test prods and briefly touching the accessible
electrode several times.
4.4 Tests with the Accessible Electrode
The tests should be carried out without the push-
buttons pressed.
Attention!
While working with the accessible electrode the
perceptibility of the display may be impaired (see
part 2 “Safety Precautions”).
Note!
Tests performed with the accessible electrode are
only possible in systems working with properly
grounded a.c. voltage systems at voltages of at least
165 V to earth.
