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.

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.

recording is in progress.
After power on, when the current flowing is greater than the Low Current trigger value. The
system automatically begins to record the accumulated capacity, energy, and time elapsed. The
‘REC’ indicator will change from red to green.
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.

differential voltage method to measure the resistance of a data connection cable
23：USB Tester directly connected to the power supply with Voltage and Current values displayed
24：USB Tester connected via a data connection cable with Voltage and Current values displayed.
25：R: 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.
Press the ‘NEXT’ button to switch to the Measurement Graphing Interface.
Interface 5: Measurement Graphing Interface
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.
Press the ‘NEXT’ button to switch to
the system parameter setting interface.

to enter into setting state, press “NEXT” button to step through the options of auto screen off
time, brightness level, temperature display units, theme background color and theme foreground
color. Stop on the value you wish to change then press the "PREV" button to change the setting.
For auto screen off time setting press ‘PREV’ to repeatedly step though the 10 options from 0
to 9 minutes. Default time is 1 minutes.
For the screen brightness setting, press ‘PREV’ to repeatedly step though the 6 options from 0
to 5 where 0 is the lowest brightness level and 5 is the highest. Default brightness is 4.
For the temperature display units, pressing the ‘Next’ button toggles the setting between C
and F. default temperature unite is C.
For theme background color, press ‘PREV’ to repeatedly step though the 7 options from 0 to 6
where the color sequence is red, green, blue, yellow, light blue, pink, white and black. Default
color is 2, blue.
For theme foreground color, press ‘PREV’ to repeatedly step though the 7 options from 0 to 6
where the color sequence is red, green, blue, yellow, light blue, pink, white and black. Default
color is 6, white.
At any setting state, press and hold the ‘Next’ button to exit the settings menu.
