FNIRSI Fnirsi USB Tester Charge Detection -FNB58 Digital Voltmeter Ammeter USB Tester TYPE-C Fast Charge Detection Trigger Capacity Measurement Ripple Measurement(FNB58 wo Bluetooth), (YH-FNB58)

Key features: 2.0-inch full-color ultra-wide viewing angle TFT LCD display, integrated USB-A, Micro-USB, Type-C interface. 0.0001 low resolution, real-time detection of subtle changes in voltage, current and power while recharging. Support automatic protocol detection Four functions curve display: Real-time voltage and current curve for view recharging curve changes in real time Abnormal recharging is found immediately. The offline curve recording support up to 9 hours offline voltage and current curve recording, show up during recharging. D+D1 voltge curve can show the recharging protocols changes and master in time. The high-speed power supplys ripple measurement curve can show you the chargers ripple measurement. PD E-MARKER CABLE DETECTION function makes it read data information of line with E-Marker chip. DASH CABLE DETECTION function makes it read DASH cable chip related data, also support cable internal resistance measurement. Support 10 sets of recharging and discharge energy data records. Built-in battery capacity calculation formula. The battery capacity can be quickly calculated from the recorded data. The BT Version: The BT version allows you to synchronous data to your mobilephone and has the APP overvoltage and overcurrent alarm function. (Only BT version has this function.)
