parts to be tested.
- The level of voltage applied is indicated by means of the
LED step indicator
- Actuate both push-buttons
level indicator
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/+
- 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).

. 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
sure a capacitive coupling to earth.
- Apply the probe tip L2/+
During the single-pole external conductor test (phase),
make absolutely sure not to touch the probe tip L1/-
and that it remains contactless.
- If an "R" symbol is shown on the LC display
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
sure a capacitive coupling to earth.
- Apply the probe tips L1/-
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
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/-
and L2/+
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.
