DC and AC Current Test: : U6 electrical tester can not only measure amps in DC, but also measure amps in AC, it can automatically measure DC current and AC current up to 600A with the open jaw.Measure Both Current & Voltage: : With our open jaw clamp ammeter, you could test current with the jaw while measuring voltage with the test leads, or test volt with test leads while measuring amp with the jaw, the test results will dual line display on the screen. Very convenience for troubleshooting motors, pumps, or other equipment.Rechargeable Batteries: : The ac dc clamp meter comes with rechargeable batteries, you will never about power problem.Infrared Thermometer: : Thanks to the smart multimeter with infrared thermemeter design. Under any function, you could switch to temperature measurement by pressing the button once. For example, when test current or voltage, you could check the heating status of high-voltage terminals, which could judge the wire connection status.VFC Function: : Pocket digital multimeter with VFC function, which can measure the output voltage or current of inverters and motors.
