SECTION 8,
continued
Table 8 is 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 mmHg. After
determining the barometric pressure from the table or a local
weather service, enter this value into the instrument (see
Sections
3.1.5 and 3.1.6 ).
Note: If the barometric pressure from Table 8 is entered in the meter, the
altitude entered in combination with this value must be 0 feet.
