143 Measuring with Galvanic Dissolved Oxygen (DO) Probes
Salinity Factor[g/l]
Option: 0 to 70 g/L
The salinity correction factor is the ratio of the solubility of oxygen in water at a particular salinity to its solubility
in fresh water at an identically specified water temperature and barometric pressure.
• With item selected press Set.
• Use the
ud keys to modify the flashing value.
• Press CFM to save the value.
Measurement Mode (Meas.Mode)
Option: DO_%Sat, DO_Conc
Allows users to select between measuring DO saturation and DO concentration.
• With item selected, press Modify for the drop‑down options list.
• Use the
ud keys to scroll between options.
• Press Select to save.
Measurement Unit (Meas.Mode)
Option: mg/L or ppm (with Meas.Mode set to DO_Conc)
Note: With Meas.Mode set to DO_%Sat, measurements are displayed in %Sat.
Averaging Samples
Option: 1 to 60
Average sampling is a software filter to minimize sensor noise and provide more stable readings. Allows users
to get a representative reading of the “average” value from flowing water.
Averaging affects measurement. If a fast response is needed, this value should be kept low.
• With item selected, press Set.
• Use the
ud keys to modify the number of samples to average.
