Calibration Note After recalibration Sea Bird enters the new calibration coefficients in the SBE 19plus EEPROM and ships the instrument back to the user with Calibration Certificates showing the new coefficients The user must enter the coefficients in the instrument configuration con file in the Configure menu in SEASAVE or SBE Data Processing Section 5 Routine Maintenance and Calibration Sea Bird sensors are calibrated by subjecting them to known physical conditions and measuring the sensor responses Coefficients are then computed which may be used with appropriate algorithms to obtain engineering units The conductivity temperature and pressure sensors on the SBE 19plus are supplied fully calibrated with coefficients stored in EEPROM in the SBE 19plus and printed on their respective Calibration Certificates see back of manual We recommend that the SBE 19plus be returned to Sea Bird for calibration Conductivity Sensor Calibration The conductivity sensor incorporates a fixed precision resistor in parallel with the cell When the cell is dry and in air the sensor s electrical circuitry outputs a frequency representative of the fixed resistor This frequency is recorded on the Calibration Certificate and should remain stable within 1 Hz over time The primary mechanism for calibration drift in conductivity sensors is the fouling of the cell by chemical or biological deposits Fouling changes the cell
