NCV non-contact voltage detection, as long as the point is close to the AC voltage, the buzzer will emit different continuous beeps according to the different strength of the signal, and the LCD will also display different number of segments according to the strength of the signal.
The button adopts touch design, which is safer and more reliable. When using touch, every time a button is triggered, the interval time is preferably greater than 1 second to avoid false triggering.
The backlight is designed for measurement in dark places or places with harsh environments, making the measurement easier and more convenient.
Zero live wire measurement: Enter LIVE live wire measurement, the LIVE character is displayed on the LCD, use a red meter to approach the live wire test point and make reliable contact with this point, and the black mark end is suspended without touching any test point.
Automatic gear recognition, zero live wire judgment, NCV non-contact test, automatic shutdown, flashlight function, on / off beep, data hold function, low battery display, backlight display, sampling rate 3 times / sec
