Five-bit or six-bit display can be switched by one button , with the maximum resolution of 0.00001, which can real time monitoring of the subtle changes in voltage, current and power during recharging. This product uses USB3.0 interface, 9 pin design, downward compatible with USB2.0,+ times the transmission rate of USB2.0.There 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 method to measure cable resistance. It is used with constant current load to easily detect cable resistance.
