4.2.1
Voltages 12 ... 690 V AC / DC
(Nominal voltage range in accordance with
IEC 61243-3)
The device indicates the type of voltage (AC / DC).
The voltage level is digitally indicated in Volt bet-
ween 12 ... 690 V on the display.
4.2.2 Voltages > 690 V AC / DC
“OL” flashing in the display warns against voltages
exceeding 690 V AC / DC.
In this case, the test procedure must be stopped
immediately!
4.3 Testing phase and phase sequence
Attention!
These tests can be performed at a nominal voltage
of at least 165 V (50 Hz) against earth.
When performing these tests, the device must be
hold closely at the handgear of the display part.
Note:
You may wear insulating gloves when performing
the tests. Tests can be impaired by unfavourable
locations, for example on wooden ladders or insula-
ting floor coverings, as well as in improperly earthed
AC voltage systems.
4.3.1 Phase test
Determination of the phase conductor occurs by
applying the test eleL1 to the conductor.
The conductor is live when “POL” appears on the
display or the red LED lights up.
Attention!
Single pole tests are not suitable for identification
the present of voltage.
4.3.2 Testing phase sequence
To determine the phase sequence between two phases
in a earthed three-phase current system apply both
test electrodes, clasp the handgear of the display part
and proceed as follows (example 230/400 V):
- Search for the phase conductors using one pole
(see phase test).
- Apply both test electrodes to the two phase
conductors (display 400 V).
- When phase L1 is applied to the test electrode
marked (+L1) and L2 to the other test electrode
appears on the LC-display for rotation is
clockwise. If
is indicated direction of rotation
is counter-clockwise.
The test result has to be checked by exchanging
the two test electrodes. The opposite direction of
rotation must be displayed.
If 230 V is displayed instead of 400 V, the neutral
conductor may have been contacted with one of the
test electrodes.
4.4 Continuity Test, Diode Test
Connect the test electrodes with the line to be
tested. With a resistance of 0 up to about 1000 kΩ
the rectangular green LED lights up and the display
shows „- - - Ω“.
The green rectangle lights up when the test elec-
trode marked “+” of the ProfiSafe LSP 4L is applied
to the anode of a semiconductor. Otherwise the
semiconductor is connected in reverse direction.
Note!
In case, in this operation mode a voltage of 12 V or
more is applied, the device automatically switches
over to voltage testing, see section 3.
