calibration is progressing and new calibration constants of “SETUP 3” are 
stored. Then, the display shows the above message to indicate that the power 
supply is ready for the OCP calibration.
If the calibration fails, a DAC CAL FAIL or ADC CAL FAIL message appears for 
one second and the display shows the CAL SETUP 3 for current calibration 
again.

to the calibration mode.
CAL MODE
A CALIBRATING message appears for several seconds to indicate that the OCP 
calibration is progressing and new OCP calibration constants of “SETUP 4” are 
stored. Then the display will return to the calibration mode.
