Preset for measurement time 
It can be set to automatic or manual,  
in real or live time. 
In case of stop of measurement by number 
of counts, the energy region has to be set 
separately. 
 
Settings for cyclic acquisition 
For cyclic measurements the number of 
cycles and the pause between them can 
be set. An automatical saving of spectra to the 
project is possible.

Fig. 20  Settings for spectrum acquisition 
To start a spectrum acquisition, click the   button. A second click will terminate the 
measurement independent of the timing mode chosen. If a preset timing condition is reached, the 
acquisition will stop automatically.  
During the acquisition a progress bar is displayed. The scaling of the bar depends on the chosen 
timing option. With fixed and automatic timing a linear scale is provided. With manual timing the 
estimated precision according to the count statistics is used as an indicator. The green range 
spans a statistical error of about 5 % to 0.1 % absolute deviation. This allows flexible timing 
according to the purpose of the analysis. 
6.3.2  Spectrum display and manipulation 
Spectrum name. As soon as the acquisition is started the settling spectrum is displayed in the 
spectrum window and a new entry is added to the spectrum list below. The default spectrum 
name is “Acquisition” or a name referring to the associated object. If a spectrum with this name is 
already contained in the spectrum list, it is automatically overwritten (automatic numbering can be 
selected, multiple objects in Objects mode and standard samples are always numbered 
consecutively).  
Change the default spectrum name into a unique name to prevent the spectrum from being 
overwritten. 
Multitasking. During spectrum acquisition other tasks such as loading stored spectra, creating 
and processing a report, setting up methods and spectra quantification can be executed within the 
current workspace.
