5.4 Pressure and Elevation
Note: If the barometric pressure from Table 5 is entered in the meter, the altitude entered in
combination with this value must be 0 feet.
Table 5 can be used to estimate the true barometric pressure at certain elevations. The
correspondence is based on the assumption that at sea level the barometric pressure is
760 mm Hg. After determining the barometric pressure from the table or obtaining it from a
local weather service, enter this value into the instrument.
