WARNING

 Never make measurement on a circuit in which the electrical potential exceeds

600V. (While the measured voltage exceeds 600V, all the voltage display LED
light up).

 Do not attempt to make measurement in the presence of flammable gases, as the

use of the instrument may cause sparking, which could lead to an explosion.

 Never attempt to use the instrument if its surface or your hands are wet. (Do not

use in rainfall).

 Keep your hands and fingers behind the barriers during measurements.
 Never unlock and open the battery case during measurements.
 Verify proper operation on a known source before taking action as a result of the

indication.

 Never attempt to make any measurement in any abnormal conditions, such as a

broken case or exposed metal parts are present on the instrument or test probes.

 Do not make any modification to the instrument.
 Extreme caution when live circuit LED flashes or lights on.
 Correct indication of LEDs is only guaranteed within a temperature range of -

10ºC up to 55ºC (<85% RH)

4. Preparation for Measurement

4.1 Auto Power-on / Self Diagnostic Test

 Auto Power-on
 Short-circuiting the probes as follows powers on the instrument automatically and

goes into a self-diagnostic test.

Instrument may power on due to the influence of static charge.

 Self-diagnostic test

WARNING

Do not use the instrument when abnormality is found at self-diagnostic test.

 Battery voltage is normal when power LED is lighting up.

When the battery voltage is below 2.4 ± 0.1V, power LED flashes or goes off.
Replace batteries according to section 7.

4.2 Trouble shooting
If the following problems occur, unlock the battery case according to section 7 in this
manual, and then lock it again 5 seconds later. Then perform the self-diagnostic test
(section 4.1).

 Self-diagnostic test cannot be performed before/after use of the instrument.
 Automatic power-off does not operate.

5. Handy Construction

With the L1 probe on the probe clip, user can change the spacing between probes
with one hand.

6. Measurement

WARNING

 Please refer to section 2 of this manual (Safety Warnings)
 Self-diagnostic test should be done prior to measurements to confirm that LED

and buzzer works properly.

 Verify proper operation on a known source before and after use.
 Keep your hand and fingers behind the barriers on the probes during

measurements.

6.1 Voltage test (double pole test)

 Connect both probes to the object under test.
 The voltage is indicated by LEDs and LCD

Live circuit LED lights up: ≥7V

 Voltage polarity is indicated in following manner:

Note

When the L2 probe + is the positive (negative) potential, the polarity indication LED
indicates "+DC" ("-DC").

6.2 Phase rotation test
L LED and R LED for phase rotation test may operate on various wiring systems,

but effective testing result can be obtained only on three-phase 4-wire system.

 Grasp the instrument firmly and connect both probes to the object under test.

(Grasp method shown as below).

 Phase-to-phase voltage is indicated by each voltage LED.
 R LED indicates that the field is rotating towards the right direction of the

"probe". With this connection, the motor will go in positive rotation.

Grasp Firmly!!!

 L LED indicates that the field is rotating towards the left direction of the probe. With

this connection, the motor will go in negative rotation.

Grasp Firmly!!!

The principle of measurement

WARNING

Make sure the object under test is not live

The instrument detects the phase rising order regarding the user as EARTH.

Note

Function of this test may not be fully achieved if the insulation condition of user or of the
equipment under test is not enough.

6.3 Continuity test

Instrument operates as follows when measuring continuity.

RX/Ω LED should be lighted and buzzer should sound continuously.

Note

In continuity mode, the instrument works in the same way as the self-diagnostic test.

6.4 Pen light function (Illuminating the measurement point)

Equipped pen light illuminates the measurement point in dimly lit area.

Pressing the pen light switch turns on the light.

Note

 The light is available while the instrument is powered off.
 Using the pen light shortens the battery life.

7. Battery replacement

WARNING

Remove the probes from any testing point when opening the battery case

WARNING

Confirm that the battery case is properly locked prior to measurements.

Batteries are dead when power LED flashes or goes off at self-diagnostic test defined in
section 4.1. Follow the procedure below and replace batteries with new ones (type IEC
LR03 1.5V).

 Unlock the battery case with a coin-shaped object.

 Pull out the battery case and replace the batteries. Insert new batteries according to

the engraving on the battery case.

 Insert the battery case into the instrument and firmly lock the case again.
