FR
Micrometer Reset
FR performs a reset of the wavelength adjust micrometers. The micrometers are moved to reference points, and then moved to the operating points as dictated by offset values contained in the instruments constants file.
The FR command is invoked as part of the RE command, or the operator may manually send the FR command if the positions of the micrometers are suspect. The FR command may be used to determine new micrometer offset values, but these values should only be changed under the supervision of qualified personnel.
FR results are recorded in the average file, MIOAVG.nnn. The layout for the MIOAVG file is as follows
| Julian Date | Measuring mode | Temperature | Cal step | Top Micrometer found at | Top Micrometer set at | Bottom Micrometer found at | Bottom Micrometer set at |
|---|---|---|---|---|---|---|---|
| 08525 | o3 | 8 | 1055 | 7173 | 7301 | 6101 | 6094 |
Associated commands
FT
The FT command performs a Find Reference FR command but only for the top micrometer in double spectrometer instruments. (Will work with a single spectrometer instrument, but will react the same as a FR command)
FB
The FB command performs a Find Reference FR command but only on the bottom micrometer for double spectrometer instruments.
