Section 2: Diving with the Monitor 3 Air

Even the smallest differences in the pressure sensors can cause two computers at the same altitude to display different altitude sectors. (Notice how the altitude sectors overlap in the illustration.) These differences are not meaningful and do not interfere with the operation of the computer. However, if there is an altitude indication while at sea level, or two computers differ by 2 altitude sectors, contact your U.S. Divers dealer for service.

Note: In order to assure optimal decompression even at higher altitudes, the 10-foot decompression stop is divided into a 13-foot stop and 7-foot stop. Therefore, the pre- scribed decompression stops, in order, are 7 ft, 13 ft, 20 ft, 30 ft ... 80 ft.

Exceeding the Altitude Limit

The Monitor 3 Air operates normally up to an altitude of 13,123 ft.. Above that (atmospheric pressure below 8.99 psi), the computer will not show any decompression information or remaining air time. Also, Pre-Dive Planning Mode cannot be started, since decompression information is not available.

If the altitude limit is exceeded, the Monitor 3 Air will display "HI" along with all the altitude sectors.
