FISCHERSCOPE ® X-RAY 219
Features of WinFTM BASIC and LIGHT
Calibration standard set Input and storing of nominal values of the used calibration stand-
ards is performed in the
Calibration standard set in the measure-
ment application of the product. After the calibration has been
performed, the
Calibration standard set contains, in addition to the
nominal values, the calculated actual values including the correc-
tion. You can use this data to create a document for monitoring the
measuring equipment.
Calculating and saving
measurement parameters
and calibration results Measurement parameters like measuring time, calibration time,
correction data, data of the last normalization and calibration, etc.
can be calculated and saved.
Library of pure element
spectra The library of pure element spectra makes measurement of pure el-
ements unnecessary when performing a calibration. This is impor-
tant in cases, where pure elements are not available.
Spectra library During the installation of the instrument the spectra of 12 or 14 el-
ements (depending on the detector type) are measured and saved
in the spectra library. Using these spectra all further spectra are
calculated by the instrument.
You can control whether the elements are measured or the spectra
of the spectra library are used during calibration.
Reference measurement The Reference measurement checks and adjusts the drift of the in-
strument. It is also used for monitoring the measuring equipment.
Stability test of the tube and
of the detector The instrument performs automatic long-term self tests to check the
primary radiation, the resolution and gain of the spectrometer (de-
tector and electronics).
Automatic reduction of the
x-ray tube current After several minutes of instrument idle the x-ray tube current is re-
duced 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 crit-
ical peak overlaps.
