The Observer software runs on a Windows platform and reads in Counts, CPM, and CPS and has the ability to collect, log, and perform statistical analysis on the data received. The data is displayed on a graph as well as digital and analog on-screen meters and can be saved or printed in various ways including a spreadsheet format. The dwell/count time can be adjusted for each point on the graph. You can also set the length of time for the count. The on-screen meters in the software have adjustable settings as well as a settable alarm in CPM. There are both visual and audio indicators, and you can play the meter click through your PC speakers.
