Display the type of PD protocol at each power-on. PD protocol is not supported. Pd2.0: supports PD2.0 protocol. Pd3.0: supports PD3.0 protocol. How to switch the display content:In the operation interface, press the K1 key briefly to switch the display voltage/current/alternate display; Press and hold the K1 key compatible with5 seconds to turn off the display of the digital tube and indicator light, and press any key to wake up. How to adjust the voltage gear:1. In the operation interface, press the K2 button briefly to enter the voltage adjustment interface, and the voltage will flash after the digital tube displays the current gear; 2. At this time, it is modified by pressing the K2/K1 key (K2 is compatible withupshift and K1 is compatible withdownshift). When shifting gears, "p7 -1" (p7: supporting 7 voltage gears in total,-1: indicating the serial number of the current voltage gear) will be displayed first, and then the voltage value of the current gear will be displayed; If the current voltage gear supports PPS step-by-step voltage regulation, the step gear indicator (20mv 100mv 1v) will be fully lit; 3. 5s Without any key operation or long pressing K1 key 2S, it will automatically return to the running interface; Note: the last gear of "P7-L", gear "L", is triggered by turns. After selecting gear L and returning to the operation interface, all supported gears will be triggered by turns (5V/9V/12V/15V/20V/PPS mode). In this mode, the stepping voltage indicator light in the operation interface will be indicated by the marquee mode; This function can be used compatible withbatch measurement of charging head manufacturers. This product has power-off memory function. Remember the voltage gear and PD mode before power-off when you power up next time.
