4. Operating Instructions

The FNIRSI-FNB58 offers a range of measurement and detection capabilities. Below are common operating procedures:

4.1. Basic Voltage, Current, and Power Measurement

To measure the voltage, current, and power of a connected device:

1. Connect the power source (e.g., charger) to the input port (USB-A IN, Type-C IN, or MicroUSB IN) of the FNB58.
2. Connect the device to be charged (e.g., smartphone, power bank) to the output port (USB-A OUT or Type-C OUT) of the FNB58.
3. The large HD display will immediately show real-time values for voltage (VBUS), current (IBUS), and power (PBUS).

4.2. Fast Charging Protocol Detection

The tester automatically detects various fast charging protocols, including Huawei FCP/SCP, Apple PD, Samsung AFC, Xiaomi, OPPO, and more. This feature helps verify charger compatibility and performance.
