2. Key functions:
Increase the key UP: short press to switch to display the input / output voltage, long press to enter the self-calibration interface
Decrease button DOWN: Short press to switch to display current / power / capacity / energy / time
Setting button SET: Long press to enter the setting interface
Switch button ON / OFF: short press to turn on / off the output; on the display voltage and current interface, long press to set the power-on state (-ON: power on default on, -OFF: power on default off), in the capacity / energy / time interface , Long press to clear the corresponding data
3. Operation instructions of setting interface:
3.1. Long press SET button to enter the setting interface;
3.2. Adjust the size of the parameter by UP / DOWN button, support long press (fast increase / decrease), short press SET button to switch the parameter to be adjusted;
3.3. On the maximum capacity (OAH) / maximum energy (OPH) / maximum running time (OHP) interface, short press the "ON / OFF" button to select the corresponding function to turn on or off, if it is turned off, it displays "----" ";
3.4. In the maximum capacity (OAH) / maximum energy (OPH) parameter interface, long press the "ON / OFF" button to select the capacity range (9.999Ah / 99.99Ah / 999.9Ah / 9999Ah, 9.999Wh / 99.99Wh / 999.9Wh / 9999Wh );
3.5. After the parameter setting is completed, long press the SET button to exit the setting interface, and the setting parameters are automatically saved;
Note:
After the product is protected, the output will be turned off. The LCD will display the corresponding protection code (LVP / OVP / OCP / OPP / OAH / OPH / OHP). The power chip itself also has various protections. If the chip itself is protected, it will display OEP.
