Function: Built-in US -A interface, micro-USB, Type -C interface, use of external 16-bit PD protocol physical chip. Real-time monitoring of charging voltage, of current, power, capacity, charging protocol, curved waveform, etc. High precision: five-bit or six-bit display can be switched by one single button, with the maximum resolution of 0.0001. High speed: USB 3.0 interface, 9 pin design, backward compatible with USB 2.0, transmission rate 10 times that of USB 2.0. < p>Data logging: This product can save 10 sets of measurement data, you can use the data you get to calculate the battery capacity, fast and convenient. Easy to operate and operate. High-precision 6-digit display: one-key switching of 5-digit/6-digit display, maximum resolution 0.00001, real-time monitoring of subtle changes in voltage, current and power during charging, and can also detect low current when the original Apple data cable is no-load. The interface is newly upgraded and the transmission rate is doubled: FNB48 uses USB3.0 interface, 9 pin design, backward compatible with USB2.0, ten times the transmission rate of USB2.0. No need to match the original data cable, you can also directly detect the charger protocol of OPPO, Huawei, OnePlus and other brands. Multiple sets of battery capacity calculation the data logging battery: FNB48 can record up to 10 sets of measurement data and can use the measured data for battery capacity calculation. Gravity sensing screen automatic flip: FNB48 has improved the screen flip function, through the gravity induction method, the screen can be flipped freely; it can also turn off gravity direction recognition and the screen can be flipped by long press. the middle button. FNB48 directly puts the battery capacity calculation formula on the tester, and the calculation result can be multiplied by 1000 to obtain the battery capacity, which is more practical and quick to calculate. Detection of the internal resistance of the cable: FNB48 uses the differential pressure method to measure the internal resistance of the cable, and is used with constant current loading to easily detect the internal resistance of the cable.
