“A”,is installed in your Monitor and have been calibrated. Suppose
the calibration data block of your Monitor contains the information
shown in Fig.12.8 (notice no filter is installed in position “E”)
Suppose You now install an optical filter in position “E”. This filter has
to be fully calibrated . Before performing a zero-point and humidity
interference task one of the following filter banks must be made
active:
· Filter bank no. 3, 4 or 5 for filter “A”;
· Filter bank no. 2, 3 or 5 for filter “B”;
· Filter bank no. 2, 3 or 4 for filter “C”;
· Filter bank no. 2, 3, 4 or 5 for filter “D”.
Suppose you make filter bank no. 3 active for all the above filters
and filter bank no. 1 active for filter “E”. Then, after a zero-point
calibration the calibration data block would contain the information
shown in Fig.12.9 . None of the original calibration data has been
overwritten by the newly-calculated calibration factors.
Note: 3434i only have an optical filter in position A
