This instrument is a compact 4-bit intelligent digital instrument with measuring ACDC voltage, resistance, disconnection, flashlight, backlight, non-contact inspection, etc. According to the input DC voltageresistance. Its performance is stable, high accuracy, high reliability, clear reading and overload protection functions. The instrument is easy to carry and is a very favorite of the majority of users.It is an intelligent tool instrument and is the ideal tool for laboratory, factory, radio enthusiasts and home. Features: 600A High Current: 600A AC and DC current measure not only has high precision, but also applies to various conductors. AC Current 600A Contactless: No need to break the skin non-contact measure of AC current, clamp head single strand measure. ManualAutomatic Range: When the screen lights up AUTO, the meter is in automatic range mode, otherwise it is in manual range mode. DC Current Measurement: Accurately measure the DC current of automobiles, TVs, stereos, etc, and adjust it to the DC current gear and clamp it with pliers. Flashlight Lighting: Turn on the flashlight to assist the night measurement work. NCV Induction Measure: There is a highly sensitive sensor on the top of the instrument that emits a beeping alarm when an AC voltage is detected.
