20 Pressing the “Calibrate” key saves the new OCP calibration constants and
return to the calibration 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.
If the calibration fails, a “OCP CAL FAIL” message appears for one second and
the display shows the “CAL SETUP 4” for OCP calibration again.
Turn off the power supply to exit the calibration mode.
Aborting a Calibration in Progress
Sometimes it may be necessary to abort a calibration after the procedure has
already been initiated. You can abort a calibration at any time by turning the
power supply off from the front panel. When performing a calibration from the
remote interface, you can abort a calibration by issuing a remote interface device
clear message or by pressing the front-panel “Local” key.
