HABOTEST AC Digital Clamp Meter True-RMS Multimeter Anto-Ranging Multi Tester Current Clamp with Amp Volt Ohm Diode Capacitance Resistance Continuity NCV Temperature Duty Ratio VFD Tests This is a dual impedance true RMS digital multimeter integrating a variety of measurements like AC/DC voltage, AC current, frequency, duty ratio, resistance, capacitance, temperature, diode, continuity, NCV, VFD, inrush current, etc.. And there are more functions like last data hold, flashlight, Max./Min./Relative value, Celsius/Fahrenheit degree, and zero key.  Features: CLAMP MULTIMETER: Measures inrush current, VFD current/voltage, AC current, AC/DC voltage, frequency, duty ratio, resistance, continuity, diode, capacitance, temperature, non-contact AC voltage (NCV) detection, and live detection. WIDE OPENING JAW: Opening jaw capacity is 40mm, wide enough to measure without disturbing the circuit. LOUD BEEP: NCV sensor send out audible and visual alarm once received electromagnetic signal. MORE FUNCTIONS: Features data hold, flashlight, low battery display, Celsius/Fahrenheit degree, Max./Min./Relative value, and Zero(reset) key. SAFE E: Designed and conforms to IEC61010-1, CAT III 1000V, safe and reliable. AUTO-OFF: Auto power off within 15 minutes if there is no operation, helps conserve the battery. MULTI TESTER: Comes with 2 test leads and a thermocouple to be used as a multitester. Note: *MUST read the user manual carefully before use for safety. *Battery not included.
