7.6. SOFTWARE OPERATION
The Model T360 Gas Filter Correlation Carbon Dioxide Analyzer has a high
performance, VortexX86-based microcomputer running Windows CE. Inside
Windows CE, special software developed by Teledyne API interprets user
commands via the various interfaces, performs procedures and tasks, stores data
in the CPU’s various memory devices and calculates the concentration of the
sample gas.

7.6.1. Adaptive Filter
The T360 software processes the CO2 MEAS and CO2 REF signals, after they
are digitized by the motherboard, through an adaptive filter built into the
software. Unlike other analyzers that average the output signal over a fixed time
period, the T360 averages over a set number of samples, where each sample is 0.2
seconds. This is technique is known as boxcar averaging. During operation, the
software automatically switches between two different length filters based on the
conditions at hand. Once triggered, the short filter remains engaged for a fixed
time period to prevent chattering.
During conditions of constant or nearly constant concentration the software, by
default, computes an average of the last 750 samples, or approximately 150
seconds. This provides the calculation portion of the software with smooth, stable
