HABOTEST HT93 Digital Multimeter Voltage Tester 2000 Counts Volt Meter Ohmmeter Auto-Ranging Accurately Measures AC/DC Voltage Resistance with NCV Live Wire Test 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. Features: 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 backlitht 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". 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". RESISTANCE MEASUREMENT: It can measure the impedance of various resistive components and cables. CONTINUITY TESTING: For resistance measurements less than 500Ω, the instrument will produce an audible beep, and the backlight will turn green. LED FLASHLIGHT ILLUMINATION: The LED flashlight allows for close inspection of contact points, making it convenient for probe measurements. AUTO SHUTDOWN: The instrument automatically powers off within 15 minutes of no operation to conserve battery power.
