Four Functions Curve Display1. FNIRSI usb tester supports real-time voltage and current curve for view recharging curve changes in real time 2. FNIRSI usb tester supports up to 9 hours offline voltage and current curve recording; 3. D+D1 voltge curve can show the recharging protocols changes in real time; 4. FNIRSI usb tester provides the high-speed power ripple measurement curve of chargers. Any abnormal charging could be found immediately.
Parameter Detection and RecordingThe Fnirsi USB tester can record 10 sets of data of the charge- discharge enegery recording and calculate the capacity of the built-in batteries. It can record 1 set of voltage and current curve up to 9hours. I supports low-speed waveform(voltage, current, D+/D-) drawing, 2sps->100sps sampling rate. It supports high-speed ripple (voltage, AC coupling)drawing, up to 4M sps sampling rate. The display of data is accurately up to 0.00001 (V/A/W).
multifunctional USB testerCompared with other usb testers, FNIRSI usb tester is multifunctional. It can measure the internal resistance of the cable by differential pressure method. It could measure the date of the cable powered by E-Marker chip and DASH cable. Besides, startup time recording, onboard temeraure measurement, PD monitoring, etc.
