Operating Instructions

When the unit is first powered on the welcome screen is displayed followed shortly by the main interface screen.

Hidden interface: Pressing any button whilst powering on the module will display three options. Option 1 selects the Chinese Interface and option 2 selects the English interface.?

The third option is to reset£¨after reset, system setting data was restored to the factory setting, all the stored data was not reset£©.Release the button at the desired selection.

Pressing and holding the button after stepping to the third option will exit the hidden interface.

?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.

To set the Current trigger value, press and hold the "Next" button to highlight the value then press the ¡®PREV¡¯ button to adjust the value as required. The value can be set anywhere between 0.01A- and 0.30A. (10mA to 300mA).

Press "Next" button to switch to the Data Connection Cable impedance Measurement Interface.

Interface 4: Data Connection Cable Impedance Measurement Interface.

The Tester can use differential voltage method to measure the resistance of a data connection cable

23£ºUSB Tester directly connected to the power supply with Voltage and Current values displayed

24£ºUSB Tester connected via a data connection cable with Voltage and Current values displayed.

25£ºR: Data Connection Cable resistance.?

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. ?

Note: If during the second step the screen turns black, this indicates that the voltage difference is too high and the tester will enter the 4V power-down state. The load current needs be reduced. Then re-start the measurement from the first step. After the Data Connection Cable resistance test is completed, the Tester needs to be powered off and then on again to resume measurement. ?

This interface displays the voltage measurement over time in the 4-24V range and will automatically adjust the displayed range in real time to account for voltage fluctuations. And the current measurement over time in the 0-5.000A range and will automatically adjust the display range in real time to account for current fluctuations.

Press and hold ¡°NEXT¡± to switch to D+D- graphing, as picture

This interface displays the D+ /D- voltage measurement over time in the 0-3.3V range and will automatically adjust the displayed range in real time to account for D+/D- voltage fluctuations.
