The
position of the cursor
on the energy scale (Bottom Left, under the
Reading number), in the form "E: x.xx KeV", where KeV is thousands of
electron volts.
The
count rate
(Bottom Left, under the energy position), in the form
“R:x.xx”.
Ka

Lg
peaks of the three elements closest to where your
cursor is positioned on the energy scale (Bottom Right). This information is
written with the element symbol first, followed by either Ka (K shell alpha
peak), Kb (K shell beta peak), La (L shell alpha peak), La (L shell beta peak),
or Lg (L shell gamma peak). An example would be "Al Ka 1.5." To
determine if a given element is present, look at the count rate at that cursor
position.
SpectraView cannot be used to determine exact element percentages in a
sample.
Multiple Spectra
SpectraView can display the reading spectra from multiple filter settings if
your analysis uses more than one filter. Use the NAV Menu to select which
spectrum to view.
The “Spectra1” choice will display the display the spectrum produced by
excitation with the first filter setting.
The “Spectra2” choice will display the display the spectrum produced by
excitation with the second filter setting.
The “Spectra3” choice will display the display the spectrum produced by
excitation with the third filter setting.
SpectraView Navigation
Use the left button on the 4-way touch pad to expand the spectrum,
centered on the position of the cursor.
Use the right button on the 4-way touch pad to contract the spectrum,
centered on the position of the cursor.
