Appendix C: SpectraView
SpectraView enables you to qualitatively analyze the fluorescent x-rays of
most of the elements in the periodic table from potassium (element 19)
through plutonium (element 94) in a given sample. For a complete list of
elements and their fluorescent x-rays see Appendix A. In SpectraView Mode,
the spectrum is displayed in a linear scale, autoscaled logarithmically so that
the highest peak on the screen reaches the top of the scale.
How to Use SpectraView
You can access the SpectraView screen after taking a measurement in any
mode, or while viewing a previous measurement, by selecting Spectra from
the NAV Menu. Once you are in SpectraView, you can use the up and down
positions of the 4-way touch pad to scroll through the spectrum, or you can
tap on the spectrum display with the stylus to place the cursor at the point
you tapped. The vertical cursor line indicates the current position along the
spectrum.
