or damaged batteries can cause cauterization on contact with
the skin; use suitable hand gloves in such cases. Ensure that
the batteries are not short-circuited. Do not throw batteries
into the fire.

WARNINGS

•

Read understand and follow safety rules and operating
instructions in the manual before using this tester.

•

The tester’s safety features may not protect the user if not used
in accordance with the manufacturer’s instructions.

•

Check on a known live source within the rated AC
voltage range of the tester before use to ensure
it is in working order.

•

Insulation type and thickness, distance from
the voltage source, shielded wires, and other
factors may affect reliable operation. Use
other methods to verify live voltage, if there is
any uncertainty.

•

Do not use if the tester appears damaged or if it is not
operating properly. If in doubt, replace the tester.

•

Do not use on voltages that are higher than as marked on the
tester.

•

Use caution with voltages above 30 volts AC as a shock hazard
may exist.

•

Comply with all applicable safety codes. Use
approved personal protective equipment
when working near live electrical circuits

Operation

Test Preparation

**NOTE: Prior to every test, please ensure that the instrument is in
perfect condition:

• For example, keep an eye out for a broken housing or leaking

batteries.

• Always carry out a function test before using the voltage tester, see

below.

• Check that the instrument is functioning properly (for example at

a known voltage source) before and after every test.

• If the safety of the user cannot be guaranteed, switch off the

instrument and secure it to prevent unintentional usage.

Power ON/OFF

• In the OFF state, press the Power/Mode Button to turn ON

• In the Power ON state, press and hold the Power/Mode Button to

shut down/power OFF

AC Current Measurements

• Put a single conductor/wire in between the opening of the

open jaw clamp and the LCD will display the current
measurement value.

• Place the wire in the correct position of the open jaw current

clamp otherwise the measurement will be inaccurate.

• The LCD will display the reading.

Voltage Measurements

Connect both test probes with power source.

The voltage is displayed via LEDs below the measured
voltage value will light up, the different indicating signals
of the voltage detector (including the ELV limit indication)
are not to be used for measuring purposes,
the voltage is also shown on the LCD display.

For AC voltage, the “AC” is illuminated; For
positive voltage, the “+” is illuminated; For
negative voltage, the “-” is illuminated.

In the case of DC voltage, the polarity of
the indicated voltage relates to the voltage
tester probe tip.

Once the safety extra-low voltage
(50VAC/120VDC) is reached or exceeded,
the “ ” is illuminated, in the event
of no battery power or main circuit failure.

Once voltage is applied to the
measuring instrument, press the
HOLD Button, the LCD and LEDs
display shows the recorded
reading; To delete the recorded
value, press the HOLD Button
once again.

Phase Sequence, Rotation (Rotary Field) Measurements

**NOTE: Effective for voltages greater than 80Vrms.

•

The voltage testers are equipped with a double­pole rotary field indicator.

•

The rotary phase indication is always active, the

symbols “R” or “L” are always displayed, however

the rotary direction can only be determined
within a thee-phase system, here the instrument
indicates the voltage between two external
conductors.

•

Connect the instrument Red Test Lead (L2+) with

the supposed phase L2 and the Black test lead
(L1-) with the supposed phase L1, the voltage
and the rotary field direction are displayed.

•

“R”signifies that the supposed phase L1 is the

actual phase L1 and the supposed phase L2 is the

actual phase L2, “L” signifies that the supposed

phase L1 is the actual phase L2 and the supposed
phase L2 is the actual phaseL1.

•

The test result table is as follows:

Resistance Test

• The Tester measures low ohm resistances between 1Ω
and 1999Ω at a resolution of 1Ω.

• Note for Resistance test to make sure the UUT (Unit
under test) is not live.

Continuity Test

• Note for Continuity test to make sure the UUT (Unit
under test) is not live.

• The continuity test is only possible when batteries
are installed and in good condition, a signal sound
is audible for continuity and the LED for continuity
LED is illuminated

.

NCV Test

• NCV cannot measure voltage, it can only sense whether
there is voltage.

• NCV induced voltage is not less than 100V., it can only
sense AC voltage.

Cleaning

Prior to cleaning, remove voltage test from all measurement
circuits.

If the instruments are dirty after daily usage, it is advisable
to clean them by using a damp cloth and a mild household
detergent.

Never use acid detergents or dissolvents for cleaning.

After cleaning, do not use the voltage tester for a period of
approx.

Battery Replacement

When the battery symbol appears on the screen, replace the
battery.

Completely disconnect voltage tester from the measurement
circuit.

Remove discharged screw, battery cover and batteries.

Replace by new batteries, two type “AA” by respecting correct

polarity.

Close the battery cover and re-screw the screw.
