Operation Guide

Readings Hold
During the measuring process, if the readings are required to hold, slightly press “ ” button ,the display value will be locked, slight press “ ” button again to cancel readings hold.

Backlight / Light
In the process of measurement, if the ambient light is too dim, causing reading difficulties, press “ ” button to open backlight and it will automatically turn off after about 1 minute.
Press “ ” button to turn on or off the lighting, it will turn off automatically after 1 minute.

Relative Measurement
Press “ REL ” button to cancel or turn on the relative measurement function, which is unavailable in the dual measurement display mode.

Auto Power Off

1. If after 10 minutes when the meter is on without any operation, it will go into hibernation and automatically shut down to save power. In the 2 minutes before power-off, the buzzer buzzes once every 1 minute.
2. After the auto power-off, the meter must be restarted to enter working state.
3. Press “APD” ” button to cancel or turn on the  auto power-off function.

Measurement Preparations

1. Turn the transfer switch, turn on the power. If the battery voltage is low (about ≤ 3.5V), the LCD will show “ ”, then the battery shall be replaced
2. When the meter has not entered into measurement, it will automatically enter the status of automatic scan, the meter displays as the following diagram shows.

Enable low-pass filter (AC current only)
Press “ LPF ” button to enable or disable the low-pass filter function. When the low-pass filter function is enabled, the low-pass filter of the measured signal is attenuated by -3dB at approximately 1 kHz.

Non-contact Voltage Detection (NCV)
Press and hold ” NCV ” key for more than 2 seconds, NCV function is enabled and the meter LCD will display.

When the NCV sensing area of the meter is close to the measured cable, the charged cable can be judged by the buzzer sound and the LED indicator on the panel.
In NCV detection mode, the meter does not measure voltage, resistance, or current at the same time.

Note: Even there is no alarm indication, the voltage might still exist. Do not judge if there exist voltage or not in the cable relying on non-contact voltage detector. The detection operation might be affected by various factors such as the socket design and insulation thickness types are different and so on.

AC/DC current measurement
Turn rotary switch to “ AUTO ” position, hold the trigger, open the clamp head, and clamp one cable of the measured circuit, and the meter will display the current value measured.

1. When the measured signal is AC current and the current value is ≥0.5A RMS, the main display of the meter shows the measured current value and the secondary display shows the frequency value of the current
2. When the measured signal is DC current and the current value is ≥0.5A, the main display of the meter shows the measured current value.

AC/DC voltage measurement
Turn rotary switch to ” AUTO “, then connect the meter probe to the measured voltage signal.

1. When the measured signal is DC voltage and the voltage value is ≥ 0.5V, the meter will display the current measured DC voltage value. When the measured signal is <0.5V, the meter will default to the resistance value and display the internal resistance value of the measured signal.
2. When the measured signal is AC voltage and the voltage RMS value is ≥ 1.0V, the main display of the meter will show the current measured AC voltage value and the secondary display will show the frequency value of the voltage. When the measured signal is <1.0V the meter will default to the  resistance value and display the internal resistance value of the measured signal.

Resistance / Continuity Measurement
Turn rotary switch to ” AUTO ” level and connect the meter probe to the measured resistor. When the measured resistance is <50Ω, the meter buzzer will buzz; when the measured resistance is >10MΩ, the meter will display “—

Dual measurement display
The meter can also measure and display the voltage or resistance value while measuring and displaying the current value by turn rotary switch to ” “.

1. Hold the trigger, open the clamp head, and clamp one. Cable of the measured circuit, when the measured signal is > 0.5A (0.5A RMS for AC current and 0.5A for DC current), the meter secondary display shows the measured current value.
2. Connect the meter probe to the measured signal, when the measured AC signal RMS value is ≥ 1.0V, the main display of the meter will show the current measured AC voltage value. When the RMS of the measured AC signal is <1.0V, the meter will default to the resistance value and display the internal resistance value of the measured signal.
3. Connect the meter probe to the measured signal, when the measured DC signal is ≥ 0.5V, the main display of the meter will show the current measured DC voltage value. When the measured DC signal is <0.5V, the meter will default to the resistance value and display the internal resistance value of the measured signal.
4. When the measured resistance is <50Ω, the meter buzzer will buzz; when the measured resistance is >10MΩ , the meter will display “—-“.
