IMPORTANT IMPACT ON READING OR DATA

A value of “XXXX” displayed for any of the TEST functions indicates an

out-of-range reading or the analyzer’s inability to calculate it. All

pressure measurements are represented in terms of absolute pressure.

Absolute, atmospheric pressure is 29.92 in-Hg-A at sea level. It

decreases about 1 in-Hg per 300 m gain in altitude. A variety of factors

such as air conditioning and passing storms can cause changes in the

absolute atmospheric pressure.

Standard deviation of CO concentration readings. Data points are
recorded every ten seconds using the last 25 data points. This
function can be reset to show O2 or CO2 stability in instruments with
those sensor options installed.
