Capacity/energy/running time statistics: Statistics start automatically after power on (ON), and the last state value is displayed after power off (OFF), and automatically restart recording after power on again; in the corresponding interface, long press the ON/OFF button for 2 seconds to automatically clear the corresponding data. Maximum capacity ()/energy (OPH) setting: When the /OPH function is enabled, when the statistical capacity/energy is greater than the set maximum capacity/energy, the power supply will automatically turn off. output and flash the display ""//OPH'; After the alarm is triggered, the capacity/energy statistics will be cleared automatically; Set maximum discharge time (OHP): When the OHP function is enabled, when the power supply running time is greater than the set maximum discharge time, the power supply will automatically turn off the output and flash "OHP"; After the OHP alarm is triggered, the time statistics data will be automatically cleared; Function,
