the USB cable and Geiger counter has been connected. A troubleshooting guide for the com port is also
included in the Appendix.
The Geiger counter must be on and connected to the computer for the program to begin graphing. To
begin graphing simply click “Start” in the lower left hand corner of the main interface screen.
The main program interface is comprised of the following components:
The main graph on which the values will be plotted.
Time options frame. This allows user to select different time units (Second, Minute, Hour,
Day) For example, if you set the time unit to Second, then the program will count the radiation
levels per second, and plot. If you set it to Minute, the program will count radiation levels per mi-
nute, and plot.
Graph type frame. This allows user to switch between different views of graph (Line Chart,
3D Line Chart, Bar Chart and 3D Bar Chart).
Plot frame. This comprises of the Start button which starts the capturing and plotting pro-
cess. When capturing is in progress, the same button will act as a Stop button, which stops captur-
ing and plotting process.
Graph frame. This comprises of a Clear button which clears the graph, a Save button which
saves values to the active file, a Save As button which allows to select a different file for saving,
and Viewer button which launches the Viewer.
mR/hr frame. This comprises of a textbox which displays current radiation level.
Serial Port frame. This comprises of a combo box which allows com port selection.
Status frame. This comprises of an LED which displays the status of the program. The status
LED changes according to the activity. When no capturing is in progress, the LED will be Off and
status will be Stopped. When the program is receiving values, the LED will be Blue and status
will be Receive. When program is writing the values, the LED will be Green and status will be
Write.
Real Time Data frame. This frame displays various real time values such as Counts Per Sec-
ond (CPS), total accumulated count (if the program is running on modes other than Second), time
left before next update, and total number of points captured.
Others frame. This comprises of a Print Chart button which allows to prints the current
plot, a Settings button which opens the Settings dialog, an About button which displays the infor-
mation about the program, and an Exit button which quits the program.
