9.1.5 Effect of Changing the UA number in the “Active”
Set-up
WARNING!: Changing the UA number of a 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 any filter is changed in the active
set-up of the Monitor, all calibration data related to the optical filter
whose number 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as it is no longer valid.
Fig.9.3 Effect of changing a UA number in the “active” set-up
For example, if the UA number of the filter installed in position “A” of
the filter carousel is changed in the active set-up then calibration
factors are deleted from the active file “A” in the Working Memory
and from files A 1, A 2, A 3, A 4 and A 5 in the Source Memory of
the monitor (see Fig.9.3). The Monitor will not be able to measure
any gas with filter “A” until it has been fully calibrated, see Chapter
12 for details.
