compensate for any offsets that may occur. These corrections are saved and used by the

software in future pointing calculations.

See also Section 8, and SE and SKC.

SKC Continuous (scheduled) Operation

SKC allows an operating schedule, created by the SE command, to be run continuously - that

is, at the end of the local day a set of summary records is produced (see ED), and the

schedule waits for the beginning of the next day and the schedule starts again.

See also Section 8, and the SE and SK commands.

Standard Lamp Test

SL initiates the most important quality assurance test in the Brewer commend set. This test

performs an "ozone" or an NO

source. The test should be run at least at the start and end of the day and should be

preceded by an HG Calibration, The values of R5, R6, and F1 should be monitored carefully,

and significant changes should be noted and investigated.

For the SL test, the iris is opened, FW#1 is set to position 1, and FW#2 is set to position 0.

See also Appendix F for details on the test.

SLSUM Standard Lamp Summary

SLSUM reads the daily Data (B) file and prints out the 'summary' results of the day's SL

tests. In addition, entries are made in the SLOAVG.nnn or SLNAVG.nnn files

The SLSUM command is usually invoked as part of the ED command.

See Appendix A for an example of the SL average files.

Azimuth Tracker Steps Per Revolution

SR initiates a test that determines the number of motor steps required for one complete

revolution (360° ) of the Azimuth Tracker.

The tracker is first zeroed in the counter clockwise direction, and a discrepancy between

where the software thought it was, and where the zero reference was found, is output. The

Tracker is then moved a full revolution clockwise and the total number of steps required for

this movement is output, The operator is given an opportunity to save the new value. A

progressive change of value over time may suggest that Tracker maintenance is required.

See Appendix F.

Tracker maintenance is covered in Section 5.

Direct Sun UV Scan

SS results in the Brewer performing a UV scan of the sun through the quartz window. The

scan is in 0.5nm steps over the range 290nm to 363nm.

Data is stored in a SSJJJYY.nnn file.

No response file is available for this mode of UV scanning.
