Table 3 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 mmHg. After determining the barometric pressure from the table or obtaining it from a
local weather service, enter this value into the instrument, see
Note: If the barometric pressure from Table 3 is entered in the meter, the altitude entered in
combination with this value must be 0 feet.

Note: The SET PRESSURE setting must be correct for proper measurement of percent saturation
and proper operation of air calibration.
Highlight appropriate sensor if more than one sensor is attached.
Select from the displayed options (mmHg or altitude in feet or meters).
