6. TAKING MEASUREMENTS

During measurement the dissolved oxygen reading is

automatically compensated for pressure and salinity. For best

accuracy, ensure the pressure and salinity settings are adjusted

accordingly from the setup menu. The factory default value for

barometric pressure is 760 mm Hg or 101.3 bar (sea level). The

factory default value for salinity is 0.0 ppt (no salinity).

See Section 5.6 — Barometric Pressure Adjustment

See Section 5.7 — Salinity Adjustment

Follow these general rules when taking measurements:

 Keep the membrane free from contact with solid

objects.

 Provide stirring of your solutionthis helps to overcome

oxygen consumption of the probe and prevents air

bubble entrapment.

 Do not submerge the cable for extended periods.

 Use with aqueous solutions only.

 The pre-assembled cap must be completely submersed

to obtain an accurate reading in solutions.

 Rinse the probe well with DI water or rinse solution

between measurements.
