This functional clamp meter provides multiple types of accurate measurement for professionals. Comes with 2 test leads and a thermocouple wire, It also features LED flashlight, backlit, auto shut-down, and data hold for more convenient use. Features: Provide accurate measurements of DC/AC voltage, AC current, resistance, capacitance, NCV, Continuity, Hertz, Diode, and temperature(/). Non-contact detection of standard voltage in cables, cords, circuit breakers, lighting fixtures, switches, outlets and wires. Live/Null wire detection. There will be an audible beep, blinking red LED, and "----" displayed on screen if detects the live line. Wide jaw opening of about 1.4in allows you to analyze the current on live conductors but don't interrupt the circuit. Readings can be clearly seen in dim-light area with backlit LCD display and flashlight features. Auto-off conserves battery if no operation within 15 minutes, and the data hold feature keeps your readings exactly where you need them. Comes with 2 test leads with dust plugs and nip caps and 1 thermocouple wire for temperature measurememt. It also has overload conservation, low battery indication, and data hold feature. Note: *Batteries not included.
