Note:
1. Do not connect power over 24V to the tester.
2. FNB38 USB-A input port supports high power input (20V * 5A = 100W etc.) The USB-A output port can withstand short 5A current, but the Micro-USB input port does not support high current and high power. The input current cannot exceed 2.5A. If you use high current and high power, we recommend using Type C female output.
3. HID-USB interface is only used for data transfer.
4.High voltage, high power will increase the temperature of tester. Beware of burns.
! When updating the firmware of the USB tester, you need to check the model first. To avoid unexpected errors, please do not update with other firmware.
