Accurately measure AC/DC current, AC/DC voltage, resistance, capacitance, diode. Easy to use in laboratory factories and homes. Features: Intelligent Voice: When the value stabilizes, the instrument starts to broadcast the reading without having to look at the screen or listen to the voice. AC Current Non Contact Safer: The SET button switches to AC to measure the current value of a single core wire, with an automatic range of 600A. NCV Non-contact Induced Electricity: The clamp head induction live screen EF will display the LED red light will flash and an alarm beep will sound. Vehicle DC Current: Clamp the single core wire with the clamp head to measure the current value of the car battery, with automatic range. DCA ACA Current: No need for wire breakage to measure 600A AC and DC current, with a maximum diameter of 34mm for the clamp. Data Retention: The measured values can be kept on the screen, and can be clearly seen even in a dark environment with a bright screen.
