14  ADDENDUM 2: PRESSURE VS ALTITUDE TABLE

Barometric pressure affects DO readings, therefore this meter lets you enter the correct

barometric pressure at your altitude. If you do not have equipment that lets you measure the

exact barometric pressure at your altitude, you can estimate it using the chart below.

If you change the barometric pressure setting from its factory setting (760 mm Hg), the %

saturation calibration value in air will automatically adjust to a value other than 100% (see

“corrected % saturation value” column below). The adjusted value is correct for the new

barometric pressure setting.

See page 20 for information on how to adjust the barometric pressure.
