Comments
Enter desired value and initiate calibration.
Example: CALS1PS 1250
Will change the current reading to 1250 µS/cm
Establish the sensor zero. With sensor in dry air,
initiate this calibration.
Enter desired value and initiate calibration.
This will take time with many ranges to calibrate.
Establish the sensor zero. With sensor in dry air,
initiate this calibration.
Put the sensor in air and initiate this calibration.
The final reading should be the amount of oxygen
in air - approximately 8 to 9 ppm depending on
temperature, pressure and salinity.
Enter desired value and initiate calibration.
Establish the sensor zero for ppb measurements.
This calibration should not be initiated without a
reliable zero reference.
Enter desired value and initiate calibration.
Once a calibration sequence has been initiated, this
command will return detailed status. See below for
details of the response codes.
Sending this command with stop any calibration
sequence currently in process and return the system
to its original state.
