4.3 Pressure & Salinity Compensated Measurements
During measurement the dissolved oxygen reading is automatically
compensated for salinity and pressure based on values entered in the setup
menu. For best DO accuracy, ensure pressure and salinity are adjusted
accordingly from the setup menu. The factory default values are 760 mm Hg
(101.3 kPa) barometric pressure (sea level) and 0.0 ppt salinity (no salinity).
See Section 5.9 — Pressure & Salinity Adjustment.
