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.
