Safety warning

This instruction manual contains warnings and safety rules which must be observed by the user to ensure safe operation of the instrument and to maintain it in a safe condition. Therefore, please read through these operating instructions before using the instrument.

• WARNING is reserved for conditions and actions that are likely to cause serious or fatal injury.
• CAUTION is reserved for conditions and actions that can cause injury or instrument damage.

This set of instructions must be adhered to. Failure to follow these instructions may cause serious injury, death, instrument damage and/or damage to equipment under testing.

WARNING

• Never take measurements on a circuit in which the electrical potential exceeds 690V. (If the measured voltage exceeds 690V, all the voltage display LEDs light up).
• After measuring AC/DC voltage for 3 minutes, the tester must not be used for 1 minute immediately afterwards.
• Do not attempt to take measurements 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 when it is raining).
• Keep your hands and fingers behind the barriers during measurements.
•  Never unlock and open the battery case during measurements.
• Always verify proper operation on a known source before taking action as a result of the indication. The unit must be proved before and after operation in accordance with safe isolation procedures.
• 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 modifications to the instrument.
• Extreme caution and danger when live circuit LED flashes or lights up.
• Correct indication of LEDs is only guaranteed within a temperature range of-10°C up to 55°C (<85% RH)

Preparation for Measurement

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.

The instrument may power on due to the influence of static charge. ALWAYS PROVE THIS TESTER ON A KNOWN LIVE SOURCE BEFORE AND AFTER TEST.

• Self-diagnostic test

WARNING
Do not use the instrument if an abnormality is found during a self-diagnostic test.

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

Troubleshooting

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-proving Test cannot be performed before/after use of the instrument.

  • Automatic power-off does not operate.

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

Measurement

Voltage test (Double-pole test)

WARNING

• Carefully check Clause 2 also.
• Self-diagnostic test should be done prior to measurements to confirm that LEDs and buzzers work properly.
• Before using a voltage tester with audible indication, please make sure that the background noise level is not such that the tester’s audible output cannot be heard.
• Verify proper operation on a known source before and after use.
• Keep your hand and fingers behind the barriers on the probes during measurements.
• 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”).

High voltage indication

• Hold the instrument firmly and connect both probes to the object under test.
• Live circuit LED lights up when a voltage of approx. 50V AC or more exists in the object under test. (Pol> 50V AC)

Phase rotation test
L LED and R LED for Phase rotation test may operate on various wiring systems, but effective testing results can be obtained only on Three three-phase system.

• Hold the instrument firmly and connect both probes to the object under test. (The holding method is shown as below fig.)
• 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 positive rotation.
• L LED indicates that the field is rotating towards the left direction of the “probe -”. With this connection, the motor will go negative rotation.

The principle of measurement
The instrument detects the phase rising order of the user to EARTH.

NOTE
The function of this test may not be fully achieved if the insulation condition of the user or of the equipment under test is not good enough.

Continuity test

WARNING
Make sure the object under test isn’t live. The instrument operates as follows when measuring continuity.

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

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

Penlight function
(Illuminating the test Point) Integral pen light illuminates the measurement point in dimly lit areas.

• Pushing the Penlight switch turns on the light.

NOTE

• The light is available while the instrument is powered off.
• Using the Penlight shortens the battery life.

Battery Replacement

WARNING
Remove the probes from any testing point when opening the Battery case. Batteries are dead when the Power LED flashes or goes off at the Self- diagnostic test defined in point 4.1. Follow the procedure below and replace batteries with new ones (type AAA 1 .5 x 2pcs).

• Unlock the Battery case with a coin-shaped object.
• Pull out the Battery case and replace the batteries. Insert new batteries according to the symbols on the Battery case.
• Insert the Battery case into the instrument and firmly lock the case again.

WARNING
Confirm that the Battery case is properly locked prior to measurements.

Safety Symbol

Measurement Category

• Category IV: is for measurements performed at the source of the low-voltage installation.
• Category III: is for measurements performed in the building installation.

For Environment

• Do not dispose of electrical appliances as unsorted municipal waste, use separate collection facilities.
• Contact your local government for information regarding the collection systems available.
• If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into the groundwater and get into the food chain, damaging your health and well-being.
• When replacing old appliances with new ones, the retailer is legally obligated to take back your old appliance for disposal at least for free of charge.

Ingress protection (IP) ratings

Ingress protection numbers are used to specify the environmental protection – electrical enclosure – of electrical equipment. The IP rating normally has two numbers:

1. The first number – protection against solid objects.
2. The second number – protection against liquids.

IP64:
The instrument is protected against dust and water sprayed from all directions.
