5 Operation
5.1 Switching on
The device automatically switches on if it detects continuity, an AC
or DC voltage above approx. 6 V, or a live phase on L2.
Alternatively, it can be switched on with the function button.
5.2 Switching off
The device is automatically powered off after 30 s if there is no
signal contacted to the probes.
The torch light switches off after approx. 30 s.
5.3 Self-test
Do not use the device during the self-test.
The self-tests starts if the device is off and both probes L1 – and L2
+ are shorted.
The self-test will start automatically when replacing batteries.
Expectedresult:AllLEDs,thebuzzer,andthevibrationswitchon
for 2 s.
If (some of) the LEDs, or the buzzer, or the torch
light do not switch on, the device is not safe for use.
Restart the self-test again. If the result is not the expected
result (see above), the device must be removed permanently
from operation and has to be secured against inadvertent use.
If the battery symbol is displayed continuously on the display, the
batteries are empty and must be replaced. See chapter „s
Exchange of batteries“.
5.4 Torch light
Pressing the function button will turn on the torch light and after
approx. 30 s it will turn itself off.
When torch light is on, pressing the function button about 6 s will
turn it off.
6 Conducting measurements/tests
6.1 General information
Before and after use, always conduct the self-test and check
that the tester is in perfect working order (e.g. on a known
voltage source).
Measurement category with screwed-on safety cap:
CAT IV 600 V, CAT III 1000 V
Measurement category without screwed-on safety cap: CAT II 1000
V
For tests/measurements of Schuko sockets, the 4 mm test tip adapt-
ers (round pins) are to be screwed onto the test tips.
Put the test tip cover on if you do not work with the device to
prevent injuries and damage to the test tips.
6.2 Voltage test with polarity indication
To determine the absence of voltage, 2 results must be
achieved: No voltage and no indication of polarity.
The voltage indication is battery independent. However,
without batteries the device only has a limited functionality:
If the batteries are empty or if there are no batteries inserted
into the device, only the LED for dangerous voltage lights
up if a voltage of 50 V
AC
/ 120 V
DC
is present.
Therefore, if possible, operate the device with batteries. See
chapter „s Exchange of batteries“.
The voltage indication (steps) via LED must not be used as
measurement. It is only an indication of voltage range.
Depending on the internal impedance (internal resistance)
of the voltage detector there will be a different capability of
indicating the presence or absence of operating voltage in
case of the presence of interference voltage.
• Low impedance voltage detectors:
A voltage detector of relatively low internal impedance,
compared to the reference value of 100 kΩ, will not
indicate all interference voltages having an original
voltage value above the ELV level. When in contact
with the parts to be tested, the voltage detector may
discharge temporarily the interference voltage to a level
below the ELV, but it will be back to the original value
when the voltage detector is removed.
When the indication “voltage present” does not appear,
it is highly recommended installing earthing equipment
before work.
• High-impedance voltage detectors:
A voltage detector of relatively high internal impedance,
comparedtothereferencevalueof100kΩ,maynotper-
mit to clearly indicate the absence of operating voltage in
case of presence of interference voltage.
When the indication “voltage present” appears on a part
that is expected to be disconnected of the installation, it is
highlyrecommendedconrmingbyanothermeans(e.g.
use of an adequate voltage detector, visual check of the
disconnecting point of the electric circuit, etc.) that there is
no operating voltage on the part to be tested and to con-
clude that the voltage indicated by the voltage detector is
an interference voltage.
• Voltage detectors with load connection:
A voltage detector declaring two values of internal im-
pedance has passed a performance test of managing
interference voltages and is (within technical limits) able
to distinguish operating voltage from interference voltage
and has a means to directly or indirectly indicate which
type of voltage is present.
• Connect both test tips to the object under test.
• Optional: By pressing both the load connection buttons simulta-
neously, an internal load will be connected, i.e. the impedance
is lowered, so that inductively/capacitively induced interference
voltagesaresuppressedanddonotinuencetheresult.
• Result:
If a life endangering threshold voltage 50 V
AC
or approx.
120 V
DC
is exceeded, the LED for dangerous voltage lights
up and the device warns acoustically and vibrates.
• The voltage is indicated by the LEDs and on the display.
• The polarity is indicated in following manner:
12 V + – LEDs light up = alternating current
12 V + LED lights up = positive direct current
12 V – LED lights up, display shows „–“ = negative direct
current
• When the L2 test tip is connected with a positive (negative)
potential, the LED 12 + (–) lights up.
During the voltage test, the L or R LED may light up. This
is due to technical reasons and does not signify anything.
6.3 Single-pole phase test
The single-pole phase test must not be used to determine the
absence of voltage.
Proper function of this test is not be fully achieved if the
grounding conditions aren’t good enough. Insulating proper-
ties can adversely affect the test.
• Connect the L2 test tip to the object under test.
• Result:
ThesinglepoletestLEDlightsupandthebuzzersoundsifa
voltageof≥100V
AC
exists in the object under test.
6.4 Rotary eld test
Measurement principle: The device detects the phase rising order
regarding the user as earth.
Correct results can be obtained only on properly grounded
three-phase 4-wire systems.
Proper function of this test is not be fully achieved if the
grounding conditions aren’t good enough. Insulating proper-
ties can adversely affect the test.
Conduct a counter test, to verify the result. To do so, switch
the test tips around; the expected result is swapped display of
the result.
• Connect both test tips to the object under the test.
• Results:
• Phase-to-phase voltage is indicated via the voltage indica-
tion LEDs.
• TheRLEDlightsupforrightrotaryeld.
• TheLLEDlightsupforleftrotaryeld.
6.5 RCD trip test
For voltage tests in systems with RCDs (residual-current device,
also ground fault circuit interrupter – GFCI), an RCD can be tripped
with a 10 m A or 30 mA nominal leakage current in a single phase
AC 230 V power system.
• Connect the two test tips L and PE.
• Push both RCD trip buttons simultaneously.
• Expected result: The RCD trips.
If the RCD doesn’t trip, the system must be checked.
6.6 Continuity test (Rx)/Diode test
Conrm that testcircuit/object is voltagefree with a 2-pole
voltage tester. See voltage tests.
• Turn the device on. See chapter 5.1 „Switching on“.
• Connect both test tips to the test object.
• Result:
• Forcontinuity(uptoapprox.500kΩ)thecontinuitytestLED
andthedeviceisbuzzing.
• If no continuity is detected, the device off after approx. 30 s.
Exchange of batteries
Empty batteries are indicated by an symbol on the display.
If the test tips are shortened and the continuity test LED does not
light up, the batteries must be replaced.
Onlyinsert batteries accordingto thespecication foundin
the technical data.
• Unscrew the battery cover and open it.
• Remove the empty batteries and insert new batteries according
to the polarity indicated on the device.
• Close the battery door and screw it closed.
Do not throw used batteries into the household trash. Observe
the local regulations for disposal.
