Dimensions: 182x62.1x33.4mm Describe: 1. 400A high current, to measure the DC current of the car, you need to manually adjust to the DCA DC current gear, and use the pliers to clamp the single-strand wire for measurement 2. Complete measurement functions, high precision and no error, can be measured without breaking the wire 3. NCV non-contact induction, the red LED light in the middle of the clamp meter flashes, and a buzzer sounds 4. With a flashlight design, it is convenient to measure in dark places at night 5. VA color reverse display screen, clear and easy to read
