• If the meter is not normal or damaged, please do not use it again.
• Before using the meter, ensure that the product is intact.
• When the “ ” symbol is displayed on the meter, replace the battery.
• Do not use the meter in an environment with explosive gas or steam or humid environment.
• When using the probe, hold your fingers behind the probe guard.
• When measuring, please connect the null or ground wire first, then the live wire; when disconnected, please disconnect the live wire first, and then the null or ground wire.

Power on / off

Press and hold the “ ” key for about 2 seconds to turn on or off.

Function selection

1. Press “FUNC” key to select function.
2. Press “FUNC” key for about 2 seconds to return to the NCV measurement.

• Power on is in NCV function mode by default.

Data hold / Flashlight

1. Press “ ” key to tum on or off data holding.
2. Press and hold “ ” key for about 2 seconds to turn on or off flashlight.

Auto power off

After power on, auto power off will be on by default and “ ” symbol will be displayed. Without any key operation in about 15 minutes, the meter will automatically shut down to save battery energy.

Measurement operation

Warning

• Do not measure the voltage higher than 600V, otherwise the meter may be damaged.
• Pay special attention to safety when measuring high voltage to avoid electric shock or personal injury.
• Before use, test the known voltage with the meter to confirm that the meter is in good condition.

NCV measurement

1. Press the “ ” key to power on into NCV measurement mode by default.
2. Gradually close the NCV sensing area to the measured conductor.

• When the weak electric field signal is detected, it will display “–L”; the buzzer will sound slowly and the green light on.
• When the strong electric field signal is detected, it will display “–H”; the buzzer will sound quickly and the red light on.

Smart (AUTO) measurement

In this mode, DC voltage, AC voltage, resistance, continuity can be measured, and the meter can automatically identify the measurement signal.

1. Press the “ ” key to power on. Then press the “FUNC” key to select “AUTO” gear, the meter displays “ ” to enter the smart testing mode.
2. Insert the red probe into “INPUT” jack and the black probe into the “COM “jack.
3. Contact the probe with both ends of the measured subject or resistance in parallel, and the meter will automatically recognize the measured signal.
4. When measuring the resistance, if the resistance value is < about 50 0 , the buzzer will sound.
5. Read the results from the display.

Note: The minimum measurable voltage of this mode is about 0.8V.

Frequency measurement

1. Press the “ ” key to power on, then press the ” FUNC ” key to select ” Hz ” gear.
2. Insert the red probe into ” INPUT ” jack and the black probe into the “COM “jack.
3. Contact the probe with both ends of the measured subject .
4. Read the results from the display.

Capacitance measurement

1. Press the “ ” key to power on, then press the “FUNC” key to select “ ” gear.
2. Insert the red probe into ” INPUT ” jack and the black probe into the “COM “jack.
3. Contact the probe with both ends of the measured capacitance .
4. Read the results from the display.

Diode measurement

1. Press the “ ” key to power on, then press the ” FUNC ” key to select “ ” gear.
2. Insert the red probe into” INPUT” jack and the black probe into the ” COM ” jack.
3. Connect the red probe to the anode of the diode and the black probe to the cathode of the diode.
4. Read the forward bias value on the display screen.

Note: If the electrode of the test wire is inversely connected with the electrode of the diode, the display will read OL , which can be used to distinguish the anode and cathode of the diode.

Live wire detecting

1. Press “ ” key to power on, then press “FUNC ” key to select “LIVE” gear.
2. Insert the red probe into” INPUT ” jack and remove the black probe.
3. Use the red probe contact to the conductor.

• When the weak electric field signal is detected, it will display “-12: the buzzer will sound slowly and the green light on.
• When the strong electric field signal is detected, it will display “—H “: the buzzer will sound quickly and the red light on.

Non-contact phase sequence detection

1. Press “ ” key to power on, then press ” FUNC ” key until “PA” symbol shows on display to enter the phase sequence detection state.
2. The letter “A” is flashing and stick the sensing probe to the first phase line of the socket and waiting for a beep:
3. Display the “PAB” with “B” flashing and stick the sensing probe to the second phase line, wait for a beep;
4. Display the “PABC” with “C” flashing and stick the sensing probe to the third phase line, wait for a long beep;
5. At the end of the test, the display will show the detection results.

• “P—L” showed on the screen indicates a left-handed phase sequence.
• “P—R” showed on the screen indicates a right-handed phase sequence.

Note : Please detect the three wires within 1 minute, if not, the detection timeout error will occur, the display shows the PABC symbol and the “P” flashes at that time. Please return and test again.
