Feature: 1. [Versatile Function] Including measuring frequency, diode, capacitance, AC DC voltage, AC current, resistor, neutral live wire testing, continuity testing, continuity buzzer, data hold, auto power off, audible and visual alerts. 2. [Auto Ranging] This digital clamp meter features auto ranging function, eliminates the need to manually switch ranges, making current measurements quick and easy. 3. [NCV Induction] There is no need for wire breakage to measure, the closer the sensing distance, the faster the alarm sound. 4. [Built in Flashlight] The clamp multimeter comes with a flashlight function for illuminating dark spaces to help locate wires, and also serves as an emergency flashlight when needed. 5. [Backlit Display] Long press the H BL button to activate the backlit for clear visibility of screen readings in low light conditions, adding convenience.
