Press the key of the coding potentiometer briefly to activate the parameter that needs to be set. The switch between parameter name and bits is accomplished by short pressing the key of the coded potentiometer. Once the parameter name is selected, it will be displayed in reverse blue, and the parameter to be set can be switched by rotating the encoding potentiometer. After selecting bits, the corresponding bit will also be displayed in reverse blue, with parameters being set through rotation of the encoder. Once settings are complete, long press the key of the encoding potentiometer for 2 seconds or more, and any inactivity will automatically exit the setting mode. All parameters will be saved automatically upon exit. Data group functionality allows for saving of 10 data groups ranging from M0 to M9. By default, the data group M0 can be saved. Press and hold the key of the coding potentiometer for 2 seconds on any interface to quickly access the M1/M2 data groups, with the current data group serial number shown at the interface. In the power parameter setting interface, selecting the data group and rotating the encoding potentiometer will allow access to the corresponding data group. After modifying the parameters in the selected data group and exiting, the parameters will be stored in the current data group by default. Set voltage U-SET: 0.6-36V; Set current I-SET: 0-5.1A; Input undervoltage protection default: 4.8V, user adjustable; Output overvoltage protection OVP default: 37V, user adjustable; Output over-current protection OCP default: 5.2A, user adjustable; Output over power protection OPP default: 81W, user adjustable; Maximum operation time OHP: If not set to 0, activating this function will automatically turn off output when the operation reaches the pre-set time; Maximum capacity: If not set to 0, enabling this feature will turn off output when the capacity reaches the defined parameter; Maximum energy OWH: If not set to 0, this function will turn off output when energy reaches the defined parameter; OHP / OWH functions can enable timed or quantitative power supply.
