Warning Tips:

1. Do not connect a power supply exceeding 24V to the tester.

2.The FNB38 USB-A input port supports high-power input (such as 20V * 5A = 100W. The USB-A output port can withstand 5A current for a short time, The Micro-USB input port does not support large current and high power, and its input current cannot exceed 2.5A. When using high current and high power, it is recommended to use Тype -C female output.

3. The HID-USB interface is only used for data transmission

4. When using high voltage and high power, the temperature of the tester will rise. Please be careful to prevent burns.

When upgrading the firmware of the USB tester, you need to confirm the model first. Please do not use the firmware of other models to upqrade to avoid unexpected errors.
