3.5 The Calibration Mode
3.5.1 Source Selection
Before entering the CALIBRATION MODE , a calibration source should be selected. By pressing NEXT , you
can toggle between the different sources (K-40, Cs-137 and Co-60). To cancel the calibration, just press
SETTINGS .
3.5.2 Checking the Calibration
The calibration has a tremendous impact on the measurement quality of the instrument. It determines
the precision of the current calibration by locating the peak at the correct position. The RADEAGLET
has a dedicated screen to visually inspect the calibration quality when performing a calibration in the
CALIBRATION MODE . The CALIBRATION MODE is accessible (the CALIBRATION icon) in the SETTINGS
MODE menu.
The following quantities are shown in the CALIBRATION CHECK screen:
• Nuclide – shows the calibration nuclide used for the check
• Measured centroid – the centroid of the measured peak (in keV)
• Measured resolution – the resolution given in percentage
• Measured FWHM – the full-width-at-half-maximum (FWHM)
• Indication whether the system can be improved
