Description:High precision display: this tester features 5-digit and 6-digit display and max. resolution of 0.00001. It can detect the real-time subtle changes in voltage, current and power during charging.Faster transmission with USB 3.0: the tester is equipped with USB 3.0 interface, whose transmission rate is 10 times more than that of USB 2.0, more energy-saving and time-saving.Record more data: this tester can record up to 10 sets of measurement data. And the calculation formula of battery capacity is equipped on the tester, which makes the calculation more convenient and faster.Sensing digital screen: the display of the screen can automatically flip with gravity sensor. And you can also turn off the gravity direction recognition to meet different demands.Easy to carry: the tester is very compact and portable. You can take it in the handbag when you are traveling, not taking much space. And it is convenient for you to store it.Specification:Material: ABS.Testing Voltage: 4 24 24 V.Testing Voltage Resolution: 0.00001V.Accuracy of Testing Voltage: ±(0.2% + 2)Current Testing: 0 6.6.5A.Current Resolution Test: 0.00001A.Current Testing Accuracy: ±(0.5% + 2).Display Power: 0 156W.Current Resolution Test: 0.00001W.Current Testing Accuracy: ±(0.5% + 2).International Equivalent Resistance Load: 0~9999.9ω.International Load Equivalent Resistance Resolution: 0.0001ω.International Equivalent Load Resistance Accuracy: ±(0.5%+2).Capacity: 0~9999.99Ah.Energy used: 0 999999.99Wh.Resistance line: 0~9999.99ω.D+/ D- Voltage: 0 3.3V.D+/ D- Voltage Resolution: 0.001V.Tension Accuracy: ±(1.0% + 2).Equipment Temperature: ℃/℉.Note:There might be a few color distortions due to different computer resolutions.There might be a slight error due to different hand measurements.Package Included:1 Piece Voltage Current Tester.
