Capacity/energy/running time statistics: the statistics will automatically start after the power is turned on (on), and the value of the last state will be displayed after the power is turned off (off), and will automatically restart the recording after the power is turned on again; In the corresponding interface, long press the power button for 2 seconds to automatically clear the corresponding data. Maximum capacity (OAH)/energy (OPH) setting: when OAH/OPH function is enabled, when the statistical capacity/energy is higher than the set maximum capacity/energy, the power supply will automatically turn off the output and flash the display "OAH"//OPH'; After the alarm is released, the capacity/energy statistics will be cleared automatically; Set the maximum discharge time (OHP): when the OHP function is enabled, when the power supply's running time is longer than the set maximum discharge time, the power supply will automatically turn off the output and flash "OHP"; After the OHP alarm is released, the time statistics data will be cleared automatically; function, can realize quantitative feeding/timing very well. Note: When 0AP/OPH and OHP functions are not turned on, the power supply will automatically save capacity/energy and running time. After the OAH/OPH and OHP functions are turned on, the power supply will automatically turn off the output after reaching the set value; Running time is in countdown mode.
