[Updated Designed USB Tester] For FNB58 USB tester has a 2.0-inch full-color ultra-wide viewing angle TFT LCD display, integrated USB-A, Micro-USB, Type-C interface. It is a high-reliability, USB voltage andcurrent detection meter and a mobile communication terminal fast chargingtrigger. automatically switch the display direction. [Multifunction USB Digital Tester] FNB58 uses external 16-bit ADC, PD protocol physical chip. It can be used to measure the power supply or power consumption of products such as USB interfaces, mobile phone chargers, and U disks. FNB58 USB tester can monitor the voltage, current, power, resistance, capacity, temperature, D+/D- voltage etc, it can be used to test the fast charging protocol of chargers. [Fast Charge Protocol Trigger Detection] FNB58 supports trigger detection of fast charging protocols, QC2.0/QC3.0 trigger, /SCP trigger, trigger, PD2.0/3.0 trigger, VOOC/WARP trigger, Super VOOC 1.0/2.0 trigger. The above protocols all support automatic monitoring. Support QC2.OPD2.0 protocol conversion. [Parameter Detection and Recording] The highest six-digit display of voltage, current and power, the highest resolution is 0.00001 (/W). 10 sets of switchable capacity, power and time statistics. 1 set of voltage and current curve records, maximum support 9 hours. Support low-speed waveform (voltage, current, D+/D-) drawing, 2sps100sps sampling rate. Support high-speed ripple (voltage, AC coupling)drawing, up to 4M sampling rate. [Other detection functions] FNB58 has many functions that other USB testers do not have. The internal resistance measurement of the wire by the differential pressure . E-Marker Cable chip reading. DASH Cable data reading. Record of startup time. Onboard temperature measurement. PD monitor. Colour:Black Material:Plastic Package Contents: 1 * Usb tester(without Bluetooth) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
