Feature: 1. NCV DETECTION: In NCV mode, move the instrument's NCV sensing probe gradually closer to the area being tested. When the instrument detects a weak electric field signal, the green backlight lights up, and the screen displays "L". When the instrument detects a strong electric field signal, the red backlight lights up, and it emits a rapid beeping sound, while the screen displays "H". 2. LIVE WIRE DETECTION: When you select the LIVE mode, connect the red probe to the test point or insert it. When the instrument detects a weak signal, the green backlight illuminates, and the screen displays "---L". When the instrument detects a strong signal, the red backlight lights up, and a rapid beeping sound is emitted. The screen displays "---H". 3. RESISTANCE MEASUREMENT: It can measure the impedance of various resistive components and cables. 4. CONTINUITY TESTING: For resistance measurements less than 500, the instrument will produce an audible beep, and the backlight will turn green. 5. LED FLASHLIGHT ILLUMINATION: The LED flashlight allows for close inspection of contact points, making it convenient for probe measurements. 6. AUTO SHUTDOWN: The instrument automatically powers off within 15 minutes of no operation to conserve battery power. Specification: A new generation of high performance digital multimeter. The new display and function layout show clearer and better user experience. It is the best choice for professional electricians, enthusiasts or families.
