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 .
Press to select the desired measurement mode:
 Percentage Saturation (%) and Temp ( º
C or
º
F)
 Concentration (mg/L or ppm) and Temp ( º
C or
º
F)
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.
