as well as warning for hazardous voltage (>50 V/AC, >120 V/DC).
Operation also possible with at batteries or without batteries
Symbol for continuity check
Battery symbol for used battery
Conformity symbol, CE-approved
Device and equipment for working under voltage. Personal
protective measures required.
Protection class 2 (double or reinforced insulation/protective
insulation)
INSERTING / REPLACING BATTERIES
Disconnect the voltage tester from the respective measurement object.
Hold both measuring tips together. If no signal sounds or an empty battery symbol appears on the display,
the batteries must be replaced. To protect your safety, attach the two plastic covers/measuring tip covers.
For this purpose, loosen the screw (18) using a small Phillips head screwdriver. Now, carefully pull the
battery compartment (17) downwards along the cable. Remove the empty batteries from the measuring
instrument, where applicable, and insert new batteries of the same type (see “Technical Data”) into the
battery compartment observing the correct polarity. The use of rechargeable batteries is not permitted. We
recommend to use alkaline batteries. They guarantee a long service life. Slide the battery compartment
back upwards until you feel it click in place and carefully close the compartment with the screw (18).

FUNCTIONALITY TEST / SELF-TEST
We recommend to test the functionality of the measuring instrument before each measurement.
Hold both measuring tips together. A signal will sound and the symbol (7) will turn on. The product is ready
for operation.
The measuring instrument switches on automatically when the respective measurement unit is detected.
After a measurement, the measuring instrument turns off automatically to save power.
If no signal sounds, replace the batteries. If functionality is not given even after replacing the batteries, the
product must not be used!
Additional self test function (all LED, TORCH, BUZZER are ON for 2 sec) is implemented for all Conrad
VTs. It can be started when VT is off. The user need to push Torch button (15) and hold for 4 sec. After that
all LED/symbols light, Torch light and buzzer sound is active for 2 sec.
Always attach the measuring tip cover if you are no longer using the device.
SINGLE-POLE PHASE TESTER
The single-pole phase tester works at a voltage of at least 100 V/AC without counter potential.
Keep in mind that the output can be affected when measuring outer conductors with e.g. strongly insulating
protective equipment or at insulating locations. The single pole detection is indicated with an LED.
A single-pole phase tester cannot be used to test de-energised conditions!
VOLTAGE TESTING/PHASE ROTATION DIRECTION
The LCD display (8) shows the measured voltage (AC/DC), the phase rotation direction <L or R>
(100 V AC and higher) and the measurement range in the bar chart. The display can be paused for
approx. 2 minutes by pressing the Hold button (16).
Connect the two measuring tips with the object to be measured.
The voltage tester automatically switches on when it detects a voltage of 12 V or higher.
When using the voltage tester in the measurement category CAT III and CAT IV, it is
recommended to attach the plastic protective covers provided to the test probes (2) and
(3) to decrease the length of the free contact tips. This reduces the risk of a possible short
circuit during testing.
For ease of use, the product has a holder (4) for a second measurement line. This makes
measuring e.g. directly via mains sockets easier.
For direct current, the polarity of the voltage displayed refers to the measuring tip of the
measuring instrument (3).
When the batteries are empty, only the warning indicator (5) for “Dangerous Voltage”
will function when the test voltage reaches 50 V/AC or 120 V/DC. Do not ever touch the
measuring contacts, if this indicator is on. Change the batteries.
CONTINUITY TEST
Before a continuity test, make sure that the measurement object is de-energised.
Connect the two measuring tips with the object to be measured. A signal will sound and the
LCD will show the continuity symbol (7) and Con, if the continuity is max. 400 kΩ +/-50%.
Disconnect the measuring tips from the measurement object after the measurement.
RESISTANCE MEASUREMENT
To activate the electrical resistance measurement function, press the “hold” button (16) for about 3
seconds. The measuring tips (1) must be free from any contact before activating this function. The
measurement unit switches to the electrical resistance measurement function.
Now you can connect the two test prods on the object to be measured.
The measured amount of electrical resistance is showed on the display.
By pressing the “hold” button briey, the measurement results can be frozen.
Make sure that the object to be measured is not under voltage!
RCD TEST (GFCI TEST)
The circuit tester can check the function of the FI.
The voltage tester can only check the function of the residual current device. The test and
tripping current, as well as the tripping time, cannot be determined!
Connect the measuring tip (2) with the protective earth conductor and the measuring tip (3) with the phase.
Press the red button (14) and the red button (14a) at the same time. The voltage tester vibrates until the
buttons (14, 14a) are pressed and FI did not react or FI is broken.
MEASURING POINT LIGHTING
The measurement device has LED illumination mounted on the top of the casing to allow measurements in
dim light. To activate this function press the button (15), press the button a second time to turn off the LED.
The LED turns off automatically after about 30 seconds to spare the battery.
MAINTENANCE AND CLEANING
Apart from the occasional battery change, the product is maintenance-free for you.
However, in order to ensure the accuracy of the measurement device over a long period, it is
recommended to have the device calibrated once a year.
Never clean the product while it is connected to a voltage source. Use a clean, dry, soft cloth for cleaning.
Do not use aggressive cleaning agents, as these can cause discolouration. To prevent scratch marks, do
not press too strongly on the surface when cleaning.
DISPOSAL
a) General Instructions
Please dispose of the unserviceable product according to the relevant statutory
requirements. Remove any inserted batteries and dispose of them separately from the
product.
b) Batteries
As the end user, you are required by law (Regulation on Spent Batteries) to return all dead batteries and
accumulators. Disposal in the household waste is prohibited.
Batteries containing hazardous substances are labelled with the symbol opposite indicating
that disposal in the domestic waste is forbidden. The symbols of the critical heavy metals
are: Cd = Cadmium, Hg = Mercury, Pb = Lead.
You can return your used batteries/rechargeable batteries free of charge to the ofcial collection points in
your municipality, in our stores, or anywhere batteries or rechargeable batteries are sold.
