Kipp & Zonen Brewer Mk III Operator's Manual page 40

B2 Standard Lamp ON
B2 turns on the internal Standard test Lamp and is useful in a command sequence (i.e.
B2ZSSL) where the ZS measurement is taken while the Standard Lamp is warming up.
Note that if the SL does not execute for some reason, the Lamp may be left on and should
be turned off with the B0 command.
CF Instrument Constants File Update
CF accesses the Brewer's Instrument Constants File and allows the operator to make
changes.
Note that the constants in this file affect the operation and calibration of the instrument, and
normally are not changed unless the instrument is undergoing recalibration or has
undergone repairs. This command requires operator input, and changes should be made or
approved only by qualified personnel. See also Appendix B.
CI Lamp Scan on Slit #1 and Slit #5
CI is used to perform a wavelength scan from 286.5 nm to 366 nm on one of the two internal
test lamps. Filter Wheels are set to positions 1 and 0, and the Iris is open. The increment of
the scan is user selectable with choices of 1, 2, or 5 Angstrom. Data can be compared with
the data contained in the Final Test Record, and is stored in the file CIJJJYY.NNN in the
\BDATA directory. A typical command sequence might be B1W1CI, where B1 turns on the
HG lamp, W1 produces a 5-minute lamp warm-up delay, and CI executes the wavelength
scan.
See Appendix A for the format of the CIJJJYY.NNN file.
The CI command requires operator input.
CO Comments
CO allows the operator to enter a comment (up to 75 characters) into the Brewer data file.
This command is useful to record information about a measurement, current weather, sky
conditions, and so on.
This command requires operator input.
CS Command Sequence
CS is similar to a command line entry at the cm->__ prompt. The operator may enter a
sequence of commands to be executed, followed by an integer which indicates the number
of times the sequence is to be repeated.
This command requires operator input.
CY Slitmask Cycles
The default value for slitmask cycling for most observations is 20. The CY command may be
used to increase or decrease this number if better statistics, or a faster measurement (with
degraded statistics) is desired.
This command requires operator input.
CZ Custom Scan
CZ allows the operator to define a custom scan. Sources may be one of the internal lamps,
the UV port, or the quartz window. The scan may be over any wavelength range within the
Brewer's UV scan limits, have any wavelength increment, and use any filterwheel
combination.
This command requires operator input. Data is stored in a CZJJJYY.nnn file. See also
Appendix A.
