Abstract
In an automatic chemical testing apparatus in which radiant energy readings are taken from a liquid sample of reacted contents comprising reagent and one or more aliquots, one per channel, of a sample fluid, a statistically large number of readings are taken on each sample. For example, in a readout cycle, 32 readings are taken on each channel for a sample. For an end point chemistry, calculation of an output value is based on the mean of a plurality of readings which are a subset of all readings. For a kinetic chemistry, the output reading is based on a slope of a curve defined by subsets of successive readings.
