3.5.3 Re-Calibrating Using the Calibration Mode
The CALIBRATION MODE allows you to recalibrate the instrument. First, perform the visual inspection of
the calibration state as explained above. If you experience a deviation between the target peak position
and the actual position, you can perform a manual recalibration. If “operative” is shown (Figure
25 , p. 34 )
a recalibration is not necessary. Otherwise, when “System can be improved” shows up, a recalibration is
necessary.

40
K
After entering the CALIBRATION MODE , it takes some time until the peak fit is established. The shown
percentage value represents the progress of acquiring the minimum counts to establish the measured
peak position. This depends on the strength of the calibration source you are using. Once the peak fit
quality is sufficient and enough counts are contained in the spectrum, the
CAL button becomes active.
You can now press CAL to perform the manual recalibration and to definitively update the internal gain.
In the example in Figure 25 , p. 34 , we used
137
Cs. Calibrations can also be done on
40
K and
60
Co.
After recalibration, the calibration check acquisition is reset and you will get an updated view of the
peak fit. You can now again inspect the results of the recalibration.

Once SYSTEM is highlighted in the ADVANCED MODE , press SELECT to enter the SYSTEM SETTINGS
dialogue. The button NEXT navigates through each user editable field of these settings.
