Features of WinFTM BASIC and LIGHT Display and Evaluation of Spectra
2.14 Display and Evaluation of Spectra
2.15 Control the XY(Z) Measuring Stage
If your instrument is equipped with a motor-driven XY(Z) stage you can use the following
functions to control the measuring stage:
Automatic reduction of
the x-ray tube current After several minutes of instrument idle the x-ray tube
current is reduced automatically. Thus, the service life of
the tube is increased and energy is saved.
Drift compensation A shift of the peak position in the spectrum is compensated
by the software. This avoids wrong results especially when
there are critical peak overlaps.
Function Description
Clear display of the sum
spectra with colored
element spectra

For the evaluation of measured spectra you can overlay
the spectrum lines of up to 24 elements in different
colors.

You can compare spectra in order to identify materials,
e.g., for material sorting.

You can compare the spectrum of an unknown material
with the reference spectra of known materials, which
are stored in a spectra library. The number of stored
spectra in the library can be increased or reduced.
Saving spectra You can save measured spectra for subsequent re-use
(e.g., for subsequent evaluation when the measurement
application changes). The spectra can be stored manually
or automatically.
Loading of spectra into
the background You can load spectra into the background of the spectra
window to compare measured and stored spectra.
Zooming spectra ranges You can zoom into an area of the spectra window by using
the right mouse button.
Function Description
Moving the XY(Z) stage You can control the move of the XY(Z) stage accurately by
clicking the mouse button in the video image.
Joystick function of the
mouse The right mouse button offers additional joystick function-
ality in the video field.
