parts to be tested.
- The level of voltage applied is indicated by means of the
LED step indicator
8
.
- Actuate both push-buttons
5
to connect the plunger coil
level indicator
4
, the 12 V LED step (+/ -) and an internal
load in the voltage tester.
- Alternating voltages (AC) are indicated by the +24 V LED
and the -24 V LED lighting up simultaneously.
- Direct voltages (DC) are indicated by the +24 V LED or the
-24 V LED lighting up. The polarity indication
J
shows the
polarity
(+ or -) applied to the probe tip L2/+
3
.
- To differentiate between low-energy and high-energy volt-
ages (e.g. capacitively induced interference voltages), an
internal load in the voltage tester can be connected by ac-
tuating both push-buttons (see section 5).
5. Load connection with vibration alert
(figure A/B
)
Both handles L1
6
and L2
7
are equipped with push-buttons
5
. Actuate both push-buttons to switch to a lower internal re-
sistance. Here, voltage is applied to a vibration motor (motor
with unbalanced mass). From approx. 200 V on, this motor is
set in rotary motion. With the voltage increasing, the motor’s
speed and vibration increases as well. The duration of the test
with a lower internal resistance (load test) depends on the level
of voltage to be measured. In order to avoid an inadmissible
warming of the device, it is provided with a thermal protection
(controlled reduction). With this controlled reduction, the speed
of the vibration motor is reduced and the internal resistance
increases.
The load connection (with both push-buttons being actuated)
can be used ...
- to suppress reactive voltages (inductive and capacitive
voltages),
- to charge capacitors,
- to trip 10/30 mA FI safety switches. The tripping of the FI
safety switch is done by testing the external conductor
(phase) to PE (earth). (figure D)
6. External conductor test (phase)
(figure C)
- Fully grasp the handles L1
6
and L2
7
, in order to en-
sure a capacitive coupling to earth.
- Apply the probe tip L2/+
3
to the system part to be tested.
During the single-pole external conductor test (phase),
make absolutely sure not to touch the probe tip L1/-
2
and that it remains contactless.
- If an “R” symbol is shown on the LC display
9
, the exter-
nal conductor (phase) of an AC voltage is applied to this
system part.
Note:
The single-pole external conductor test (phase) can be carried
out in an earthed mains from 230 V, 50/60 Hz (phase to earth)
on. Protective clothing and insulating conditions on site might
impair the function.
Attention!
The absence of voltage can only be determined by means of
a two-pole test.
7. Phase sequence test
(figure E/F)
- Fully grasp both handles L1
6
and L2
7
, in order to en-
sure a capacitive coupling to earth.
- Apply the probe tips L1/-
2
and L2/+
3
to two external con-
ductors (phases) of a three-phase mains and check whether
the external conductor voltage of e.g. 400 V is applied.
- A clockwise phase sequence (phase L1 before phase L2)
is given, if an “R” symbol is shown on the LC display
9
.
Nothing is shown on the LC display, if no clockwise phase
sequence has been detected.
- The phase sequence test always requires a countercheck!
If the LC display shows the clockwise phase sequence by
means of the “R” symbol, the LC display must show noth-
ing during the countercheck with the probe tips L1/-
2
and L2/+
3
being inverted.
If the LC display shows the “R” symbol in both cases, the
earthing is too weak.
Note:
The phase sequence test can be carried out in an earthed
three-phase mains from 230 V, 50 / 60 Hz (phase to phase)
on. Protective clothing and insulating conditions on site might
impair the function.
