IMPORTANT SAFETY INFORMATION
Please read these instructions carefully before use and retain for future
reference.
• When using electrical appliances basic safety precautions should always be
followed.
• The voltage detectors are designed to be used by skilled persons in accordance
with safe methods of work.
• The voltages marked on the voltage detector are nominal voltages and the voltage
detector is only to be used on installations with the specied nominal voltages.
• The different indicating signals of the voltage detector are not to be used for
measuring purposes.
• Before using a voltage detector at locations with a high background noise level, it
has to be determined whether the audible signal is perceptible.
• It is important to check the state of the batteries (not included) before use and
replace if necessary.
• Voltages above 75V DC or 50V AC may pose a serious shock hazard.
• Before using the meter check for physical damage to the casing, in particular
around the connectors. If the case is damaged do not use the meter.
• Check the test probes for damaged insulation or exposed metal. Check the leads
for continuity.
• Do not apply more than the rated voltage, as marked on the meter, between the
terminals or between any terminal and ground.
• Do not use or store the meter in an environment of high temperature, high
humidity, an inammable nature, or where a strong magnetic eld exists.
• Disconnect the circuit power and discharge all high voltage capacitors before
testing resistance, continuity and diodes.
•The meter may only be opened by a qualied service technician for calibration and
repair.
• Remove the batteries if the meter is not in use for a long period of time.
• Ensure the batteries are inserted correctly, observing the plus and minus marks on
both the batteries and the compartment.
• Fit a full set of batteries at one time.
• Remove dead batteries from the meter, or if it is not going to be used for a long
time.
• Never mix old and new batteries together, or different types of batteries.
•Never dispose of batteries in a re, or attempt to recharge ordinary batteries.
• Clean the instrument using a soft, dry cloth.
• Do not use any chemicals, abrasives or solvents that may damage the instrument.

MEASURING
• Before measuring, perform a self-test of the unit.
• Connect the two test probes L1 and L2.
• The continuity LED will be lit and an audible tone will be heard.
• Before any test, check the unit on a known voltage source.
VOLTAGE TEST
• Always hold the test probes by the
handles behind the nger guards.
• An audible tone will be heard when an AC
voltage and a negative DC voltage are
indicated.
• The maximum switch-on time is 30
seconds. When this time has elapsed you
must wait 10 seconds before retesting.
• Connect the probes to the voltage source,
observing polarity of the test probes.
Note: L2 is the positive probe, while L1 is
the negative.
• For AC voltage the value is indicated
on the three LEDs and on the LCD. The
positive and negative LEDs will illuminate
and the buzzer will sound.

• For DC voltage, connect the L2 probe to
the positive terminal and L1 to the negative
terminal.
• The voltage is displayed on the LEDs and the
LCD. The positive LED is illuminated.
• If the polarity is reversed the buzzer will
sound and the negative LED will illuminate.
SINGLE-POLE VOLTAGE DETECTION
• Perform a function test prior to this test.
• This unit can be used as a single-pole voltage
detector when batteries are inserted.
• The single-pole test is intended only as a
quick check. The circuit must be checked
again for the presence of voltage using the
two-pole method.
• Connect the L2 test probe to the voltage
source and keep your nger on the contact
electrode.
• If an AC voltage above 100V is present, the
LED will illuminate and the buzzer will sound.
• The single-pole test can be negatively
affected by unfavourable conditions such as
an electrostatic eld or strong insulation etc.
CONTINUITY TEST
• The continuity test is only possible when
batteries are inserted and in good condition.
• Ensure the circuit under test is not live.
• Connect the L1 and L2 test probes to the
circuit. The continuity LED will illuminate and
the buzzer will sound.
•The unit indicates continuity below 400kΩ.

PHASE ROTATION TEST
• Perform a function test prior to this test.
• This unit can determine the phase rotation
within a three-phase supply.
• Connect the L2 test probe to the supported
phase 2 and the L1 test probe to the
supposed phase 1. If the R LED illuminates
the phases are in the correct sequence 1
to 2.
• Connect the L2 test probe to the supposed
phase 3 and the L1 test probe to the
supposed phase 2.
• If the R LED illuminates, the phases are in
the correct sequence 2 to 3.
• Connect the L2 test probe to the supposed
phase 1 and the L1 test probe to the
supposed phase 3.
• If the R LED illuminates the phases are in
the correct sequence 3 to 1.
• During phase rotation, test touch the
contact electrode. If the LED illuminates
then the phase sequence is anti-clockwise.
