Data Acquisition Figure-01
Please be aware that some of the screens have been altered to protect from identity theft. For example, some of the names in the "Personnel File" may appear to be real people with real Social Security numbers, but these have been altered.

Upon opening the data acquisition window you will find that you have three options:
Clicking on any of these three will bring the system into the background counting mode, as seen in the screen capture below.
Data Acquisition Figure-02 This screen should look quite familiar when you compare it to the DOS data collection screen:
In the DOS program, you would press "Escape" to stop the background collection. In the Windows version of the "Helge" program you click on the "Stop" box in the lower right corner.
Data Acquisition Figure-03 Notice how the screen has changed, in fact, if you look in the lower right corner where the "Stop" is located, you will see the cursor from the previous step and that the word "Stop" has been grayed out. Looking in the lower right-hand corner, you see that you have three options:

Let us take a closer look at the the "Counting Wizard" screen, shown below.
![]() Data Acquisition Figure-05 This is the Counting Wizard screen. You will note that there are three options:
We shall examine each of these three options, but in reverse order, starting with "Repeat counts for individuals." |

The names shown in the left screen capture come from the "Personnel Database," which is a database file from that is unique to a particular site. Each whole body counting system will have a database that pertains to that whole body countimg system. As you will note from this screen capture, you may type in an individual's name in the box at the top or you may use the scrollbar on the right to search for the name. The software is written, however, so let as you type each character of the individual's last name, the display changes to show names beginning with those characters. For this example I am going to jump directly to make a whole body in the next word a count for a Mr. Jack Chadwick. See this screen capture immediately below.
Data Acquisition Figure-06 You should look at the data and verify that this is the person for whom you wish to perform a whole body count. You have two choices at this point:
Having clicked "Next," we obtain the next screen where the "Job Title" and the "Employer" boxes have been filled from their respective databases for this individual. Note that the "Reason for Count" has an option for choosing from a defined list, or you can add a new reason for the count to this list and the size of this list is determined only by the amount of disk storage space. In the old DOS program you could only have nine reasons for a count. Therefore, the next step is to either choose to reason for the count or accept the one shown here. Clicking "Next" brings us to the next screen.
Data Acquisition Figure-07 We are almost ready to perform a count. Clicking "Next" brings up the following screen. Let us assume that the carriage is positioned correctly, which will be the normal condition. In this circumstance, the following screen will appear:
Data Acquisition Figure-08 We are now ready to start the count, so click the "Start Counting" box. Because it is possible that the carriage was not positioned correctly, let us consider that condition before we show the actual counting screens. We see this screen if the carriage is not at one of the left or right limit switches. The operator should look at the position of the carriage and if it is not at a limit switch, you have three options (see these options below the following picture):

We are now ready to see the actual data collection screens. I have chosen to collect two screen captures during the two-minute count that is being made so that we may see a change in the spectrum being obtained as well as see the profile information as a function of distance (time). Here is the first of these pictures.
Data Acquisition Figure-11 This first screen capture was taken after 61 seconds of elapsed time. Look in the upper right-hand corner to see how much time has elapsed. (There is no human being counted in this example, rather, we are using a weak cobalt-60 check source mounted about 5 inches below the detector in a stationary position. It is difficult to tell, but the experience eye will note that the "profile" has risen slightly in about the past 20 seconds. You can just see the beginnings of the two cobalt-60 photopeaks in the spectral data.
Data Acquisition Figure-12
Data Acquisition Figure-13 This screen capture was made just after the end of the count. Actually, when the count ends there is a blue background message that flashes on the screen, but its duration is so short that it cannot be captured. The program moves directly into the data analysis portion of the program and, as a result, we see the data analysis results in the previous picture. A detailed description of each of the areas in the above picture is already given in the chapter on Data Analysis.
