manufacturer, model, serial number, and the detector description. The final line
contains relevant information on acquisition status, background status, etc.
f. The bottom section of the screen contains the menu items and button bar. The menu
items will be discussed in detail in the next section. The button bar consists of a
green circle (grayed out when an acquisition is active), a red circle (grayed out when
not actively acquiring a spectrum), and a black X. Tapping the green circle will begin
an acquisition, the red circle stops an acquisition, and the black X will clear the
spectrum (after giving a warning and opportunity to cancel the deletion).
Menu Items
1.
File Menu
The File Menu contains functions generally related to
storage and retrieval of data.
a. File|Save Spectrum allows the current spectrum to be
saved to a standard “.usf” file, compatible with the
MODEL 970 MCA software for the PC.
b. File|Load Spectrum to Live loads a stored spectrum into
the “live” acquisition display. This is especially useful in
offline mode to view and re-analyze stored spectra.
c. File|Load Library File loads a different library file to be
used for analyzing samples for radioactivity.
d. File|Exit will terminate the connection and exit the application (after presenting a
warning and an opportunity to cancel).
2.
Util Menu
The Util Menu contains functions generally related to
calibration, detector settings, and analysis.
a. Util|Start Acquisition performs an identical function to
the green circle on the button bar; it begins a sample
acquisition. A checkmark will appear next to this menu
item while an acquisition is active.
b. Util|Stop Acquisition performs an identical function to
the red circle on the button bar; it stops a sample
acquisition. A checkmark will appear next to this menu
item when the MODEL 970 is not actively acquiring data.
c. Util|Clear Spectrum performs an identical function to the black X on the button bar; it
will clear the spectrum (after giving a warning and an opportunity to cancel the deletion).
