where (in the Source Memory) to store the calibration factors
calculated during the calibration task.
Fig.9.2 The state of the Source Memory after completion of a
CALIBRATION TASK
After completion of a calibration task the calibration factors, which
are found in the Working Memory, are entirely dependent upon the
Filter Bank No., which is active for the optical filter. If Filter Bank
No. 1 is active for the filter in positions “A” then calibration factors
from files A 1, W will be found in Working Memory (see Fig 9.2).
9.1.5 Effect of Changing the UA number in the “Active”
Set-up
WARNING!: Changing the UA number of the filter in the Monitor’s
active set-up will destroy all calibration data for the filter.
As explained in section 9.1.1 , the UA No. determines the set of
Optical Filter Factors used during the calculation of calibration factors
and therefore, if the UA number of the filter is changed in the active
set-up of the Monitor, all calibration data related to the optical filter
has been removed from the set-up is automatically deleted from
both the Source Memory and the Working Memory as it is no
longer valid.
