MPACT 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.
