Taking a Reference Background spectrum
Once you have installed your UATR, and before you use it for the first time, you should
consider taking a background spectrum which will act as a reference background for use with
those Ready Checks that need one for comparison purposes, including the
Contamination
Check
described on page 11.
NOTE:
For information about taking a background spectrum, see the Spectrum on-screen
Help.
