Safety Statement
Warning: Operation that may cause danger to users.

Safety Instructions

The meter conforms to IEC61010-1 CAT.Ill 600V overvoltage safety standard and pollution level 2.

Safety Specification

warning
To avoid possible electric shock or personal injury, please strictly observe the following specifications:

• Operate the meter according to the manual.
• Take care when measuring values exceed 60V DC, 30V AC RMS, or peak value 42V.
• 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.

Product Overview

1. Input Terminal
2. Signal Intensity Indicator
3. LCD Display
4. Function Key
5. Input COM Terminal

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 AUTO measurement.

Power on is in AUTO measurement mode by default.

Data hold / Flashlight

• Press “ ” key to turn on or off data holding.
• 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.

Smart (AUTO) measurement
This measurement mode is default when power on. 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, display “AUTO” and enter the smart measurement mode.
2. Insert the black probe into the “COM” jack.
3. Contact the probe with both ends of the measured subject or resistance (parallel), and the meter will automatically recognize the measured signal.
4. When measuring the resistance, if the resistance value is < about 50 Q, 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 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, “nF” signal will be displayed on the screen.
2. Insert 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 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. You can use the red probe contact to the conductor to test wires.

• 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.

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.
   a) The letter “A” is flashing and stick the sensing probe to the first phase line of the socket and waiting for a beep;
   b) Display the “PAB” with “B” flashing and stick the sensing probe to the second phase line, wait for a beep;
   c) Display the “PABC” with “C” flashing and stick the sensing probe to the third phase line, wait for a long beep;
   d) 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.
