Key function:
Add key UP: Short press switch to display input/output voltage and long press to enter self-calibration interface
Reduce DOWN: Short-click Switch Display Current/Power/Capacity/Energy/Time
SET: Long Press Enter Settings Interface
Switch key ON/OFF: Short press on/off output; In the display voltage and current interface, long press on the set boot state (-ON: power on default opening, -OFF: power on default closing), in the capacity/energy/time interface, long press clear corresponding data.
Setting up interface operation instructions:
1. Press SET button to enter the setting interface.
2. The parameters are adjusted by UP/DOWN keys to support long press (fast increase/decrease) and short press SET keys to switch the parameters to be adjusted.
3. In the maximum capacity (OAH)/maximum energy (OPH)/maximum running time (OHP) interface, press the "ON/OFF" button to select the opening or closing of the corresponding function, and if closed, display "--";
4. In the maximum capacity (OAH)/maximum energy (OPH) parameter interface, long press the ON/OFF button to select the range of capacity (9.999Ah/99.99Ah/9999999Ah, 9.999Wh/99.999Wh/99999999Wh);
5. After setting the parameters, press the encoder potentiometer for a long time, exit the setting interface and save the parameters automatically.
Note: After product protection, output will be turned off, LCD will display the corresponding protection code (LVP/OVP/OCP/OPP/OAH/OPH/OHP) power chip itself also has various protection, if the chip itself is protected, OEP will be displayed.
