NOTE

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.
