This window correction method offers a large
advantage to users running with probe barrels
permanently installed in a reactor or other
vessel. At initial set-up, the window difference
is measured and stored in Vision.
At periodic maintenance intervals, the fiber
optic bundles can be removed from the barrels,
which are now permanently installed.
The instrument and fiber optics can be calibrated for wavelength and Reference Standardized
response, without using the Transmission Probe barrels. After this is done, the fiber optic bundles are
put back into the permanently installed barrels, and the Window Correction is re-applied. This assures
consistent response, without removing the barrels.
Because the spectroscopic response of various fibers is dependent upon length and other factors,
screens will not be shown. Instead, the message boxes are given, in the order in which they appear.
Be sure the fiber probe ends are securely installed into the barrels (outer probe part) and proceed
using this set of instructions.
From the Diagnostics menu, select Create
Window Correction.
NOTE: Window Correction must be enabled
under Configure, Options. When enabled, a new
DCM must be created for Window Correction to
take effect.
Vision requests a standard file. Select the file
“TSSZERO.da” as shown, from the C:\Vision
directory.
This file corrects the fiber optic path for the
effects of the barrels (windows) being installed.
