A detailed flow diagram is provided at the end of Sec. 7 to guide you through the calibration routines.
Oxygen sensors generate a current directly proportional
to the concentration of dissolved oxygen in the sample.
Calibrating the sensor requires exposing it to a solution
containing no oxygen (zero standard) and to a solution
containing a known amount of oxygen (full-scale standard).
Automatic air calibration is standard. The user simply
exposes the sensor to water-saturated air.
To calibrate oxygen:
1. Press the
MENU
button
2. Select
Calibrate
. Press ENTER.
3. Select
Sensor 1
or
Sensor 2

Air calibration criteria can be changed. The following
criteria can be adjusted:
Stabilization time (default 10 sec.)
Stabilization pH value (default 0.05 ppm)
Salinity of the solution to be measured (default
00.0 parts per thousand)
The adjacent screen will appear to allow adjustment of
these criteria”
