+With the counts, concentration can be calculated. The basic formula used to calculate concentration is,
+    Conc (#/m^4) = Counts / (SA * Airspeed * Binsize change)
+Where,
+  * SA is sample area which is (probe arm length * height)
+        * Height is (number of diodes * diode size)
+  * Binsize change is the (Max_Size - Min_Size) for each channel.
+        * For channel 1, this would be 0.50 - 0.40 = 0.10
