 Press the ‘ ? ’ button to enter the interface as shown above: 

Press and hold the ‘NEXT’ button to switch Data Group. The USB tester can provide a total of 10 groups of data to save and view. These are numbered 0-9.

 With Data Groups 1-9 selected the current mAh and mWh are saved after power off. They will continue accumulating the next time the tester is powered on. When the data group selected is 0 then the current value of mAh and mWh will be temporarily saved at power off. When the device is next powered on these values will be recalled and will begin flashing. When the accumulated mAh exceeds 1 mAh, the previous data will be cleared and accumulation will restart.

With a Data Group selected, press and hold the ‘PREV’ button to clear the mAh and mWh.

Measurement procedure:

First, connect the USB Tester directly to the power supply and adjust the appropriate load current (recommended value 1A) . Press and hold the ‘NEXT’ button to begin recording data. The indicator prompt will stop flashing . 

Second, unplug the USB Tester and then reconnect it to the power supply via the Micro USB/Type-C IN data connection cable and adjust the load current to the same value as in the first step. Press and hold the ‘NEXT’ button to begin recording data. The indicator prompt stops flashing and the Data Connection Cable resistance measurement test is completed and the value displayed.
