1. -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 changes in voltage, current and power during recharging.2. This product uses USB3.0 interface, 9 pin design, downward compatible with USB2.0,+ the transmission rate of USB2.0.There is no need tousetheprimarydata cable, it can also directly test the recharger agreement of some mobile phones.3. This product can record 10 sets of measurement data, you can use the data you to calculate the capacity of battery.4. This product directly the calculate formula on this product, the multiply 1000 to the capacity of battery.5. This product support read the data of E- and DASH cable, and the of e- and DASH cables can be easily read after connecting the data lines.6. 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.7. This product uses differential pressure to measure cable resistance. It is used with constant current load to easily detect cable resistance.Model: FNB48SVersion: with BluetoothMonitor voltage: 4~24VMonitor voltage resolution: 0.00001VMonitor voltage accuracy:(0.2%+2)Monitor current: 0~6.5AMonitor current resolution: 0.00001AMonitor current accuracy:(0.5%+2)Monitor power: 0~156WMonitor current resolution: 0.00001WMonitor current accuracy:(0.5%+2)Load equivalent resistance: 0~9999.9Load equivalent resistance resolution: 0.0001Load equivalent resistance accuracy:(0.5%+2)Capacity: 0~9999.99AhEnergy used: 0~9999.99WhCable resistance: 0~9999.99D+/D- voltage: 0~3.3VD+/D- voltage resolution: 0.001VD+/D- voltage accuracy:(1.0%+2)Equipment temperature:/color:BlackMaterial:PCB+metalPackage Contents:1 x Protocol Capacity Test ToolOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
