>> Centbase = level used to compute AreaPSD & Centroid.
2. Use right click to start dual cursor measurement for:
AreaPSD, Width, Base (via user positioned cursors)
a. Position data cursor to right of area to measure,
using right click on graph at desired location.
b. Then right click Area toolbar icon and this will
change the data cursor to a dashed line.
c. Now position a second data cursor to left of area
at desired location on graph with right click.
d. Right click Area toolbar icon to display the
AreaPSD, Width, and Base measurements.
e. Right click Area toolbar icon to resume with
normal data cursor as a solid line.
Key words on horizontal menu: Sco Abs Tran Irad
Click on these words to quickly switch modes.
Equivalent to selecting the View menu options:
View -> Scope mode = Sco
View -> Absorbance = Abs
View -> Transmission = Tran (also used for reflectance)
View -> Irradiant Watts = Irad
