Instructions:
Hide the interface:long press and hold any key and then power on will display three
options(as the following picture show). The first item is to set the Chinese language,
the second item is to set the English language, and the third item is the current zero
calibration (when the function is performed, no load access must be guaranteed).
Keep pressing and holding the key to move shadow in turn. Release the key at the
selected item to execute the setting. If the button is still not released after three
items are displayed, it means that no function is performed and will exit the hidden
option interface.
Main interfaceⅠ: (main measurement interface)
1: Voltage measurement
2: Current measurement
3: Cumulative capacity value
4: Cumulative energy value
5: Temperature display
6: Data group number
7: Load equivalent impedance
8: Power measurement
Short press "help" button, the interface is as shown above:

https://www.banggood.com/Wholesale-Module-Board-c-2152.html
Long press the "Next" button to switch the data group. The meter can
provide 0-9 total 10 groups of data to save and view. When the data
group is group 1-9, the current capacity is stored when the power is
turned off, and will continue to accumulate when the power is turned on
next time. When the data group is group 0, the current capacity is
temporarily saved when the power is dropped. The next time the power
is switched on, it will flash to remind the last capacity. When the
accumulative capacity exceeds 1mAh, the last data will be erased
automatically, and the accumulations will start again.
Under the selected condition of the data group number, long press the
“Help” key to clear the accumulated capacity value and accumulated
energy value in the data group of this group.
Short press "Next" button to switch to the main interface Ⅱ(fast
charge identification interface):
Main interfaceⅡ(fast charge identification interface):
D+: DP, positive data signal

https://www.banggood.com/Wholesale-Module-Board-c-2152.html
D-: DM, negative data signal
Mode display: The product will automatically recognize the fast charge
mode, temporarily identifying only the QC2.0 and CQ3.0 modes. Other
mode recognition is temporarily not supported.
Short press "Next" button to switch to the main interface Ⅲ(data
record interface):
Main interface Ⅲ(data record interface):
Accumulated capacity
Cumulative energy value
Time display: cumulative time of current load
Stop current
REC: indicates the recording status, red REC means stop, and green REC
means recording.
After power-on, when the current is greater than the stop current, the
system begins to record capacity and energy, the time increases, and the
REC changes from red to green. Press and hold the “Next Page”button

to select the stop current. Short press the button to adjust the value in
turn, and the stop current can be set between 0.01 and 0.30A.
Short press the "Next" button to switch to the main interface Ⅳ(wire
group measurement interface):
Main interface Ⅳ(wire group measurement interface):
1. The voltage current value of the tester directly connected to the
power supply.
2. The test instrument is connected to the voltage current value when
the data line is connected to the power supply.
R: DATA wire resistance
This product's interface can be used to measure the data line resistance
value, the operation steps:
The first step: the tester directly connect the power supply, adjusts the
appropriate load current (Recommendation 1A), long press the “Next”
button to record the data, and the right indicator icon stops flashing.
Step 2: Unplug the tester and connect the tester to the power supply

through the Micro USB data cable. The load current is adjusted to the
same current as the first step. Long press the “Next Page” button to
record the data, and the right indicator icon will stop blinking. After the
resistance test is completed, the data line resistance value is displayed.
Note: If the tester screen turns black after inserting the data cable in the
second step, it means that the pressure difference is too large, the tester
enters the 4.5V power-down state, and the load current needs to be
reduced, need to measurement from the first step. After the wire
resistance measurement is completed, the measurement is restarted
after the tester is powered on the next time.
Short press the "Next" button to switch to the main interface Ⅴ
(voltage curve interface):
Main interface Ⅴ(voltage curve interface):
This interface is voltage measurement waveform diagram. It
automatically changes the range within the range of 4.5-24V
measurement and displays voltage fluctuations in real time.

Short press "Next" button to switch to the main interface VI (current
curve interface):
Main interface VI (current curve interface):
This interface is the current measurement waveform diagram. It
automatically changes the range within 0.00A-3.00A measurement range
and displays current fluctuations in real time.
Short press "Next" button to switch to the main interface Ⅶ(setting

Long press the "next page" button to select the delay screen time,
brightness level, temperature unit switch. Long press the "Next" button
to enter the off screen time setting, select corresponding number, short
press to cycle through the value changes, the value of a total of 10 values
in the 0-9 cycle change, in which 0 is the long bright.
Long press "Next" button to enter the screen brightness settings, select
corresponding number, short press to change the size of the number, the
greater the number, the brighter the screen, a total of 6 settings.
Long press the "Next" button to enter the temperature unit switch,
select corresponding number, short press to switch between 0 and 1. 0 is
Celsius and 1 is Fahrenheit.
Long press the "Next" button to exit the modification settings.
