Operation Instructions
Voltage DC or AC/Frequency/Resistance/Measure Continuity
- Insert the red test lead into the “INPUT” terminal, black test lead into the “COM” terminal.
- Connect the test leads in parallel to the circuit, power supply, tested resistor. The meter automatically Identify whether it is AC voltage, DC voltage or resistance, and shows the frequency on the screen.
- When resistance is less than 30Ω, the buzzer sounds.
- When measuring DC voltage, it can also show the voltage polarity of the red test lead.
- Read the measurement results from the display.Voltage DCVoltage AC FrequencyResistanceMeasure Continuity

Measure Continuity
Warning:
- Do not input voltages higher than 500V, showing higher voltages are possible, but it may destroy the meter.
- When measuring high voltage, be careful to avoid electric shock.
- Disconnect the test leads from the circuit when completed measurement.
Non-contact AC voltage detection
- Press the power button.
- Put the sensor head into the power outlet or near the electrified lead wire, and when the tester detects the AC voltage signal, the voltage signal flicks the signal, the bar value of the meter screen lights up, and the test is based on the intensity of the signal detected, lighting the corresponding signal strength indicator lights (high, medium, low), and the buzzer emits different frequencies of the alarm sound.
- Push the inductive head of the tester close to the wire, plug the probe into the jack. The tester detects that one of the strong induced signals is a live wire, and the weak or non-sensing signal of the induction signal is the neutral wire.Non-contact AC voltage detection
Warning:
- Non-contact AC voltage and live wire detection operations may be influenced by the socket design, insulation thickness, and class.. Even without indication, the voltage may still exist. Do not use a non-contact voltage detector to determine whether the voltage existence.
- When input voltage, the non-contact voltage sensing indicator may light on because of the existence of induced voltage
- Outside environment (such as flash, motor, etc.) may influence the non-contact voltage detection.
Infrared Temperature-Testing
- Press the power button.
- Press and hold to keep infrared temperature-testing.
- The tester infrared temperature sensing area close to the object 5-10cm (recommended distance).
- Read the measurement result from the display screen, and view the dynamic change of the value through the analog bar.
- You can turn on the flashlight to assist in observing the test range area, and the lighting range area is basically the same as the infrared temperature sensing range area.
