Press the CALIBRATE button to initiate the calibration or click EXIT to return to the main measure screen.
Once the calibration has been initiated it will take between 30 seconds and 2 minutes depending on sensor and temperature
measurement stability. During this period, the abort sequence can be initiated as shown with the active ABORT button.
.
When the point has been successfully calibrated, measured values will be based on the new calibration. The reading will be
in the range of 8 ppm to 10 ppm depending on the atmospheric pressure setting. Consult dissolved oxygen tables for more
specific information on expected readings after an AIR calibration.
Exiting the calibration menu will return the user to the measure screen.
