Details of keys and functions:
The type of PD protocol is displayed each time the power is turned on
'-- ': PD protocol is not supported
Pd2.0: support for the Pd2.0 protocol
Pd3.0: support for the Pd3.0 protocol
How to switch display content
In the operation interface, press K1 key to switch the display voltage/current/alternate display; Press K1 button for 5 seconds to turn off the digital tube and indicator light display.
How to adjust the voltage gear
1. At the operation interface, press the K2 button to enter the voltage adjustment interface. The voltage will flicker after the digital tube displays the current gear;
2. At this point, the K2/K1 button is pressed to modify (K2 for blocking, K1 for blocking). When the block is switched, the "p7-1" (P7: a total of 7 voltage blocking positions are supported,-1: the serial number of the current voltage blocking position) is displayed first, and then the voltage value of the current gear position is displayed. If the current voltage shift supports PPS step voltage regulation, the step shift indicator (20mv 100mv 1v) will be fully lit.
3. 5s without any key operation or long press K1 button 2S, automatically return to the operation interface;
Note: the last gear "L" gear of "p7-l" is the rotation trigger gear. After selecting the L gear to return to the operating interface, all supported gear positions will be triggered in turn (5V/9V/12V/15V/20V/PPS mode). This function can be used for batch test of charging head manufacturer.
Note: generally speaking, the charging head of PD2.0 supports the voltage regulation mode of 4-5 gears, and it will display the format of "p4-1" or "p5-1"; generally speaking, the charging head of PD3.0 supports the voltage regulation mode of 6-7 gears, and it will display the format of "p6-1" or "p7-1"
How to adjust the voltage in PPS step mode
1. First make sure that the PPS stepper indicator (20mv 100mv 1v) is fully lit/one of them is lit;
2. Long press K2 button to enter PPS voltage regulation, the digital tube voltage value flashes, first activate 1V step-down voltage regulation;
3. Press K2 again to switch the stepping position;
4. After selecting the corresponding stepping position, modify the voltage by pressing K1/K2 key; When the stepper indicator light is fully on, press K1/K2 button to exit PPS voltage regulation mode and select other voltage gears.
5. 5s without any key operation or long press K1 button 2S, automatically return to the operation interface;
This product has power off memory function, remember the voltage shift and PD mode before power off next time.
Product application:
1. This product can trigger voltages of different gears in the PD charging head to supply power to external devices, such as routers, lightcats, set-top boxes or laptops (adapter replacement should be realized under the condition that the power of PD charging head meets).
2. It can be used for batch testing and aging of PD charging head manufacturers
