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, are used by the CPU to compute the concentration using the above formula. Every 6 seconds the M450 completes a measurement cycle consisting of a 2 second wait period for the sample tube to flush, followed by a 1 second measurement of the
