Features: NCV voltage sensing: Use the NCV part on the top of the multimeter to sense. When AC voltage is detected, the screen will display ---- and an alarm will sound. The closer the distance, the more urgent the alarm. Neutral and live wire judgment: In Live mode, insert a single test leads into the hole for judgment. Live: The screen turns red and emits a quick beep; Neutral: The screen displays Live without response. Flashlight, backlight screen: The design of the double flashlight illuminates the front for you. Turn on the screen light, and you can see the screen value clearly in a dark environment and read it easily. Intelligent fuse protection: Built-in fuse, intelligent anti-burn protection, effectively prevent short circuit and fear of damage to the instrument, making measurement more secure. Silicone protective cover: The silicone protective cover is anti-fall, real material protects the body, and effectively prevents falling to protect the hardware from damage, giving you a full sense of security. Test leads input terminal: The test leads is tightly connected with the multimeter, which is firm and lasting. You no longer have to worry about damaging the instrument by inserting the wrong test leads for measurement.
