Please read theentire instruction manual before using theproduct and

have any questions concerning technical problems please contact our
CustomerServices.
Safety
Warning!
• Contact with live conductors can lead to electric shocks with serious
consequences.
• Never use thevoltage detector whilst your hands arewet.
• Never measure voltages over 1000 V AC or under 5 V AC.
Nevermeasure V DC.
• Never use thevoltage detector if any of its parts are missing, if it has any
visible defects or if it is not working properly.
• Do not disassemble thevoltage detector. Itcontains no user-serviceable
or adjustableparts.
• Do not expose thevoltage detector to extreme temperature or humidity.
• To avoid electric shock, NEVER hold thepart of thevoltage detector in
front of thefinger guard when testing voltage.
• Thevoltage detector is not designed for testing shielded cables/
components.
• If thePhase (Live) and Neutral conductors are close to each other,
itmight be impossible to determine which of them iswhich.
• Thesensitivity of voltage detector can be adjusted which can mean that
voltages might not be indicated, depending on thesensitivity setting.
• If there are several cables and 2-phase or 3-phase cables are close to
one another, try to separate them and measure each cable individually.
Explanation of theTEST BEFORE USING warning
on theproduct
Thevoltage detector should always be tested on aconductor which
is known to be live before it is used to test anunknown power source.
NEVERuse thevoltage detector to test for anunknown voltage across
acomponent if thevoltage detector did not indicate thepresence of voltage
on aknown power source.
Care and maintenance
Clean thevoltage detector using asoft, moistcloth.
Only use amild detergent; never use solvents or strong, abrasive cleaning
agents for cleaning as these can damage thevoltage detector.
Disposal
This product should be disposed of in accordance with local regulations.
Ifyou are unsure how to proceed, contact your local council.
Description
• Thevoltage detector is designed to indicate whether or not atest object
is conducting electricity.
• When it detects avoltage, thered LED indicator will flash and thebuilt-in
buzzer willsound.
• This is anon-contact voltage tester for detecting 50/60 Hz AC voltage in
therange: 5–1000 V.
• It is suitable for checking fuses/circuit breakers in consumer units and
electrical sockets, indicating breaks in cables and finding which one of
thebulbs has blown in astring of fairy lights connected in series.
• Built-in LED light with on/off switch.
Operating instructions
Note: Before thevoltage detector is used, it should first be tested on
aconductor which is known to belive.
1. Switch thevoltage detector on using thepower switch/sensitivity dial
– theindicator light will flash twice to show that thevoltage detector is
working. Thereafter theindicator light will flash at afew seconds interval
to show that thevoltage detector is switchedon.
2. Placethetest probe close to theobject to be tested (such as awire or
socket). Moveit along thelength of theobject. Adjust thesensitivity by
rolling thedial to suit thetest object.
3. Whenvoltage is detected, thebuzzer will sound and thered LED
indicator will flash in quick succession.
4. Remember to switch thevoltage detector off after testing to save
thebattery.
Note:
• If testing amulti-core cable – move thetest probe along thecable, don’t
just test one point; thevoltage detector indicates phase and thewires
in thecable might be twisted. Thevoltage detector cannot be used
on shielded cable, cable in trunking or cable behind panels or metallic
surfaces.
• Do not rub theend of thetest probe before use; this can cause
thevoltage detector to indicate static electricity generated by therubbing.
• When testing for breaks in acable – move thetest probe along thecable
for as long as thebuzzer sounds. Theplace where thebuzzer stops is
probably abreak in thecable.
• False indications could occur if thetest probe is held too close to objects
which are statically charged or if theprobe is held close to ferrous
objects close to AClines.
Adjusting thesensitivity setting
1. Turnthevoltage detector on using thepower switch/sensitivitydial.
2. Thesensitivity is adjusted by rolling thesensitivity dial – thehigher
thesensitivity, thegreater thedetection range (distance), but thehigher
thesensitivity, themore susceptible thedetector is to electromagnetic
interference.
3. Itis recommended that you begin on alow sensitivity setting and
gradually increase it to thedesired level according to thetask athand.

3. Finger guard – to avoid electric shock, never hold onto thepart of
thevoltage detector in front of thefinger guard when testing voltage.
4. Powerswitch/sensitivity dial – roll theknob backwards to switch
thevoltage detector off and forwards to switch thevoltage detectoron.
Thedial also adjusts thesensitivity – decrease thesensitivity by rolling
thedial forwards, increase it by rolling thedial backwards.
5. Pocketclip
6. Switch – Press this button to turn theLED lighton.
7. LED indicator – this red LED will flash at short intervals (and abuzzer
will sound) when AC is detected, theLED will flash at longer intervals to
indicate that thevoltage detector is switchedon.
Changing thebattery
• When thevoltage detector is switched on theLED indicator will flash
twice in quick succession if thebattery is charged. Ifthere is no initial
2-flash indication when thevoltage detector is switched on you should
change thebatteries.
• Always change both batteries at thesametime.
1. Switch thevoltage detector off using thepower switch/sensitivitydial.
2. Carefully push thebattery cover in thedirection of thearrow until it is
released.
3. Remove theold batteries and insert two new (LR03) batteries,
observingthecorrect polarity.
4. Push thebattery cover back on until it locks intoplace.
