SBE 9plus and 25
Sea-Bird software (SEASAVE or SBE Data Processing) uses calibration coefficients programmed in a configuration
(.con) file to convert raw data from these instruments to engineering units.
Follow this procedure to correct the pressure:
1. With the instrument in the air, place it in the orientation it will have when deployed.
2. In SEASAVE, in the .con file, set the pressure offset to 0.0.
3. Acquire data in SEASAVE, and display the pressure sensor output in decibars.
4. Calculate offset = (0  instrument reading).
5. Enter the calculated offset in the .con file.
Offset Correction Example:
Pressure displayed at elevation is -1.655 db. Offset = 0  (-1.655) = + 1.655 db
Enter offset in .con file.
SBE 16plus (RS-232 version), 19plus, and 49
Sea-Bird software (SEASAVE or SBE Data Processing) uses calibration coefficients programmed in a configuration
(.con) file to convert raw data from these instruments to engineering units. These instruments are also able to directly
output data that is already converted to engineering units (pressure in decibars), using calibration coefficients that are
programmed into the instrument.
Follow this procedure to correct the pressure:
1. With the instrument in the air, place it in the orientation it will have when deployed.
2. In SEASAVE, in the .con file, set the pressure offset to 0.0.
3. Acquire data in SEASAVE, and display the pressure sensor output in decibars.
4. Calculate offset = (0  instrument reading).
5. Enter the calculated offset in the .con file.
6. Also enter the calculated offset in the instrument (use the POFFSET= command in SEATERM).
Offset Correction Example:
Pressure displayed at elevation is -1.655 db. Offset = 0  (-1.655) = + 1.655 db
Enter offset in .con file and in instrument.
SBE 16plus (RS-485 version) and 16plus-IM
Sea-Bird software (SEASAVE or SBE Data Processing) uses calibration coefficients programmed in a configuration
(.con) file to convert raw data from these instruments to engineering units. These instruments are also able to directly
output data that is already converted to engineering units (pressure in decibars), using calibration coefficients that are
programmed into the instrument.
Follow this procedure to correct the pressure:
1. With the instrument in the air, place it in the orientation it will have when deployed.
2. In SEATERM, set the pressure offset to 0.0 (#iiPOFFSET=0) and set the output format to converted data in
decimal form (#iiOUTPUTFORMAT=3).
3. Acquire data using the #iiTP command.
4. Calculate offset = (0  instrument reading).
5. Enter the calculated offset in the instrument (use #iiPOFFSET= in SEATERM).
6. Also enter the calculated offset in the .con file, using SBE Data Processing.
Offset Correction Example:
Pressure displayed at elevation is -1.655 db. Offset = 0  (-1.655) = + 1.655 db
Enter offset in .con file and in instrument.
