Select 1-POINT SAMPLE from the calibration menu to begin a dissolved oxygen span calibration.
When the 1-point sample method is chosen, the status box will prompt the user to enter the desired calibration value.
This calibration should be initiated when the sensor is in a liquid that is at the high end of the expected measuring range.
Stable temperature and sensor readings will also help to establish an accurate calibration.
Once the desired value for calibration is entered, the CALIBRATE button becomes active. Once the displayed sensor and
temperature values are stable and near expected values, click 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.
