2.13 Calibrating and Monitoring of the Measuring Equipment
Function Description
Calibration of new or
existing products The obtained calibration data are stored.
Standard-free calibration You can calibrate without calibration standards by means of
the fundamental parameter method.
Standard-based calibra-
tion with the use of up to
64 standards You can correct the standard-free calibration by calibrating
with calibration standards. Thus, the accuracy of the anal-
ysis and thickness measurements is improved.
Matrix-specific calibration standards and pure element cali-
bration standards are available. Up to 64 calibration stan-
dards can be used for each measurement application.
Calibration standard set Input and storing of nominal values of the used calibration
standards is performed in the
Calibration standard set in
the measurement application of the product. After the cali-
bration has been performed, the
Calibration standard set
contains, in addition to the nominal values, the calculated
actual values including the correction. You can use this
data to create a document for monitoring the measuring
equipment.
Calculating and saving
measurement parame-
ters 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 elements unnecessary when performing a calibration.
This is important in cases, where pure elements are not
available.
Spectra library During the installation of the instrument the spectra of 12 or
14 elements (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 instrument. 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 (detector and electronics).
