The measuring spot is dependant on the collimator and the measuring distance. Typical values are 30 µm – 3 mm.
Most of our XRF instruments are full protection instruments with a design approval according to the German X-ray Ordinance.
One can measure elements from the atomic number 11 and coating thicknesses from approx. 0.005 µm to 60 µm. This depends on the ambient medium (Air, He, Vacuum), detector, size of measuring spot and the atomic number, and of course the application.
With the export mask one can define, which parameters will be exported and when and where the data will be sent to. The measurement data will then be available as a text file.
The measurement accuracy may vary depending on the measuring application: it’s a function of the measurement time, the measurement spot and the uncertainty of the standards with which the XRF device was calibrated.
Here, a scattering spectrum is required. There’s no need to measure the scattering spectrum; it can be loaded from the menu: General ► Load Spectrum and Evaluate…
The super software is not activated.
Most probably, the option File ► Print Single Readings has been activated in the menu. In this case, each individual value is sent to the printer buffer; then, once a page is full, it’s printed automatically. Deactivate Print Single Readings and clear the printer buffer.
If single readings in the block were deleted, a dash will appear in the list of measured values. These measurements can be displayed again in the menu Evaluation ► Undelete Reading. However, if all the measured readings of a block or product were deleted, the data cannot be restored.
