This digital AC clamp meter is a stable and reliable instrument with micro IC and dual integral AD transformer as the core, coming with full ranges overload protections circuit. It can be used to test AC current, AC/DCvoltage, resistor, diode, circuit continuity. A perfect troubleshooting tool that will help you solve electrical problems in the car, industrial or at home quickly and safely. It can be widely used to detect parameters such as current and voltage of electrical equipment, to detect faults in circuits and to verify the proper operation of electrical equipment. Features: High Accuracy Clamp Meter: This digital clamp meter is a stable and reliable instrument with micro IC and dual integral AD transformer as the core, coming with full ranges overload protections circuit. It can be used to test AC current, AC/DCvoltage, resistor measurement, diode test, continuity tset. Digital LCD Display with Backlight: It has a digital backlit display, with maximum display 4000 counts and reading height of 12mm, so you can read the data clearly when working in dim or low-light conditions, like electrical closets, under buildings, behind appliances, and in other enclosed spaces, and the convenient LED flashlight illuminates a dimly light area. Multi-Function Design: Auto-ranging clamp meter with multiple functions in one, data hold, LED flashlight, auto power off after 25 minutes no operation, warning light, SEL intest mode( select between diode, resistor and continuity), etc. NCV Test: NCV detect can easily and quickly determine whether there is a voltage, without touching the wires. Built-in NCV sensor probe, when strong AC signal is detected, red light turns on and buzzer sounds. Multipurpose Design: A perfect troubleshooting tool that will help you solve electrical problems in the car, industrial or at home quickly and safely. It can be widely used to detect parameters such as current and voltage of electrical equipment, to detect faults in circuits and to verify the proper operation of electrical equipment.
