-SC is normally a factory pre-calibration test and determines the optimal operating position of the diffraction grating(s) for taking ozone measurements. Each individual scan is saved to a SCJJJYY.NNN data file, the SC output average values are added to the SCOAVG.NNN file. This command can be used in schedules. A set of good sun scans taken between zenith angles of 48 and 66 degrees will provide useful information preliminary to an ozone re-calibration.
