FNIRSI FNB58 USB Tester, Digital Voltmeter with Bluetooth

• 【Multifunctional USB Digital Tester】Equipped with an external 16-bit ADC and a physical chip that supports PD protocol, FNB58 can measure the power supply or power consumption of USB interfaces, mobile phone chargers and U disks. With this USB tester, you can monitor voltage, current, power, resistance, capacity, temperature, D+/D- voltage and more. It can also be used to test the fast charging protocol of chargers.
• 【Specially Designed USB Tester】The FNB58 USB Tester is a reliable USB voltage and current meter with a 2.0-inch full-color TFT LCD display that offers an ultra-wide viewing angle. It has built-in USB-A, Micro USB and Type-C interfaces, making it compatible with various devices. Thanks to the gravity sensor, the display automatically adjusts its orientation for convenient use.
• 【Fast Charge Protocol Trigger Detection】The FNB58 supports trigger detection of various fast charge protocols, including QC2.0/QC3.0, FCP/SCP, AFC, PD2.0/3.0, VOOC/WARP and Super VOOC 1.0/2.0. All of the mentioned protocols are automatically monitored, and it also supports MTK-PE auto-detection. It even provides QC2.O to PD2.0 protocol conversion.
• 【Parameter detection and recording】With a maximum of six digits, the FNB58 displays voltage, current and power with the highest resolution of 0.00001 (V/A/W). It allows you to switch between 10 sets of capacity, power and time statistics. In addition, it offers a set of voltage and current curve recordings with a maximum recording time of 9 hours.
• 【More Detection Features】The FNB58 offers additional features that make it stand out from other USB testers. It can measure the internal resistance of the cable using the differential pressure method and read E-Marker cable chip and DASH cable data. The tester records power-on time, performs onboard temperature measurement and enables PD monitoring. It also supports analog DASH cable functionality.

Precautions

Please do not connect the monitoring port to a power supply of more than 28V;

Please do not connect the PC online port to a power supply of more than 16V;

Only one pair of monitoring interfaces (one input port and one output port) can work at the same time; when one pair of monitoring interfaces is working, it is forbidden to access devices in other monitoring interfaces. (Except for the PC online port, the PC port can be connected to an external power supply);

When using the fast charge trigger module, please do not connect devices that cannot tolerate high voltage to any of the monitoring interfaces.
