The intensity of light is converted into a voltage by the detector/preamp
module. The voltage is converted into a number by a voltage-to-frequency
(V/F) converter capable of 80,000 count resolution. The digitized signal,
along with the other variables, is used by the CPU to compute the
concentration of ozone using the above formula.
