Thermo Electron Corporation VIII-10 Orion Star Series Meter
Dissolved Oxygen Technique
2 . To initiate the Winkler titration calibration, press . The
“cal” indicator will light up .
3 . While the electrode signal is stabilizing, the meter will
flash a dissolved oxygen reading (based upon the current
calibration data) in the main field . Once the input has
stabilized, the concentration value, which corresponds to
saturation at the current temperature, pressure and salinity,
will be displayed .
4 . The concentration value should then be adjusted to the
value that was obtained via the Winkler titration . Use
/ and to enter value . Press to accept the
concentration value .
5 . The slope value ( ) will then be displayed for three
seconds . The meter will then return to measure mode .
Probe Zero Calibration
If the expected sample range is at the lower end of the
dissolved oxygen scale, you may want to perform a zeroing
of your probe . If the probe exhibits any residual current, this
calibration will compensate for it . A Probe Zero calibration
should always follow as the second point determination of a
two-point calibration . To remove the effects of a Probe Zero
calibration, perform an Air, Water or Winkler calibration as a one-
point calibration . To perform a Probe Zero calibration, follow the
steps outlined below .
