Counting Samples
Conducting Count Single Rack
Counting a Single Rack with the Default Parameters
A permanent set of default parameters can be used to obtain a quick count of samples under
Count Single Rack. The default parameters, shown in Figure 3.3, provide a window of 0 to
1000, the entire 2000 KeV energy range of the instrument and a counting time of 1.00
minute. The results are presented as cpm.
IC# (or H# Plus, If Installed) and Lum-Ex (If Installed) are turned on. Only the counting time
may be changed.
To perform Count Single Rack:
1. With the Main Menu displayed, highlight “Count Single Rack” and press SELECT. The
Count Single Rack Menu shown in Figure 3.3 is displayed.
2. To count without any changes in the program setup, press SELECT.
To change the counting time, highlight “Counting Time”. Enter the desired counting time
(0.01 to 999.99 mlns.). Highlight “Count
Any Isotope”, and press SELECT.
NOTE The counting time is not permanently stored; following the count of the one rack, the counting time is
reset to 1.00 minute.
