1-point Contacting
Conductivity Sample
CALS1PS X
Where:
X = Desired number in µS/cm
Enter desired value and initiate calibration.
Example: CALS1PS 1250
Will change the current reading to 1250 µS/cm
Contacting
Conductivity ZERO
CALSZERO
Establish the sensor zero. With sensor in dry air,
initiate this calibration.
Toroidal
Conductivity
1-point Sample
CALS1PS X
X = Desired number in µS/cm
Enter desired value and initiate calibration.
This will take time with many ranges to calibrate.
ZERO
CALSZERO
Establish the sensor zero. With sensor in dry air,
initiate this calibration.
Dissolved
Oxygen
AIR Calibration for
Dissolved Oxygen
CALSAIR
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.
1-point
Dissolved Oxygen
Sample
CALS1PS X
X = Desired number in ppm
Enter desired value and initiate calibration.
ZERO for
Dissolved Oxygen
CALSZERO
Establish the sensor zero for ppb measurements.
This calibration should not be initiated without a
reliable zero reference.

Calibration Status
CALSTATUS
Once a calibration sequence has been initiated, this
command will return detailed status. See below for
details of the response codes.
Abort Calibration
CALABORT
Sending this command with stop any calibration
sequence currently in process and return the system
to its original state.
