4.3.4 Setting up a Monitoring Task
The optical filters in the monitor have to be calibrated before they
can be used to measure gas concentrations. The user can only set-up
a monitoring task using those optical filters which have been
installed. In this example we have chosen to measure gas A (that is,
to measure gas A’s concentration using the optical filter installed in
position “A” of the filter carousel) and water vapour.
If your Monitor has only been calibrated to measure with another
filter (for example, the filter in position “B”) then choose gas B to
replace gas A in the following instructions. The parameters which
describe the monitoring task we shall set-up, are listed below:
