-
Test the voltage tester with familiar voltage sources, e.g.
with a 230 V socket.
-
Do not use the voltage tester, if the voltage indication, the
phase indication and the vibration motor are not working
properly!

Checking the absence of voltage of an installation
(figure B/C)
For checking the installation, please test the absence of vol-
tage by checking the voltage indication, the phase indication
(the phase indication only works in an earthed AC voltage
mains) and the vibration motor (the vibration motor is activated
by actuating both push-buttons). The installation is only free
of voltage, if all three test circuits (voltage indication, phase
indication and vibration motor) are signaling the absence of
voltage.

Apply the two probe tips L1/+

-
The voltage tester switches on automatically as soon as a
voltage ≥ 6 V is applied.
-
The level of voltage applied is indicated by means of the

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).
Voltage test < 6 V (low-volt) (figure D)
In order to measure voltages lower than 6 V, short-circuit the
probe tips L1/-

-
In the low-volt range, voltages from 1.0 V to 11.9 V can be
measured.
-
After being activated, the low-volt range is active for ap-
prox. 10 seconds.
-
By applying a voltage ≥ 12 V, the device automatically
switches over to a higher voltage range.
Note:
In the low-volt range, the frequency indication

. Here, voltage is applied to a vibration motor (motor with
unbalanced mass) in the display handle L2
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 con-
trolled 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 RCD safety switches. The tripping of the
RCD safety switch is done by testing the external conduc-
tor (phase indication) to PE (earth). (figure F)

The single-pole external conductor test (phase indication)

tions on site might impair the function.
Attention!
The absence of voltage can only be determined by means of
a two-pole test.
