This instrument is a compact 4-bit intelligent digital instrument with measuring AC/DC voltage, resistance, disconnection, flashlight, backlight, non-contact inspection, etc. According to the input DC voltage/resistance. Its performance is stable, high accuracy, high reliability, clear reading and overload conservation 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. Manual/Automatic 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.
