usb tester question

Hiya,

I have a usb tester which I bought basically to be able to monitor current my load pulls. The problem I am encountering is that when I connect the usb, it gives me both the current of the load plus that of the circuit. I want to measure only the current of the load. The usb tester I am using is from yzxstudio. Anyone has used usb tester before or have some ideas how I can achieve this please? Thanks.

Please ignore. I was able to find it out. Wanted to delete the message, but could not find the option. Thanks anyway.
