This instrument is a compact, 4-bit, intelligent digital instrument that allows you to measure AC/DC voltage, resistance, disconnection, flashlight, backlight, non-contact control, etc. According to the input voltage/resistance of direct current. Its operation is stable, high accuracy, high reliability, clear reading and overload protection functions. The device is easy to carry and is a favorite tool of most users. It is a smart tool and is an ideal tool for laboratories, factories, radio enthusiasts and home. Features: High current 600 A: AC and DC current measurement 600 A not only has high precision, but also applies to various conductors. 600 A Non-contact: No need to break the skin, non-contact AC measurement, single core measurement with clamping head. Manual/Automatic Range: When the screen is illuminated by AUTO, the meter is in automatic range mode, otherwise it is in manual range mode. DC measurement: Accurately measure direct current in cars, TVs, stereo sets, etc. and adjust it to DC current transmission and clamp it with pliers. Flashlight lighting: Turn on the flashlight to help with nighttime measurements. NCV induction measurement: There is a highly sensitive sensor at the top of the instrument that emits an audible signal when AC voltage is detected.
