Five-bit or six-bit display can be switched by one button , with the maximum resolution of 000001, which can real time monitoring of the subtle changes in voltage, current and during recharging. This product uses USB30 interface, 9 pin design, downward compatible with USB20,+ times the transmission rate of USB20There is no need to use the primary data cable, it can also directly test the recharger agreement of some mobile phones. It is in small size, so you can take it with you to anywhere you want to use it, or you can take it and share it with your friends. This product can record 10 sets of measurement data, you can use the data you get to calculate the capacity of battery. This product directly add the calculate formula on this product, the result multiply 1000 to get the capacity of battery. This product support read the data of E-Marker and DASH cable, and the chips of e-marker and DASH cables can be easily read after connecting the data lines. This product support screen flip function, through the gravity-induction, the screen can be free to flip, you can also turn off gravity-direction recognition and flip the screen by long pressing the middle key. This product uses differential pressure to measure cable . It is used with constant current load to easily detect cable .
