SBE 32 Carousel SBE 17plus V2 SEARAM It is possible to use the SEARAM to record 9plus data in memory at the same time as the 9plus data is transmitted real time through the 11plus Deck Unit This provides a data back up in case there are data transmission problems over the sea cable The 9plus is supplied with a powerful Windows 2000 XP software package SEASOFT V2 which includes e SEATERM terminal program for easy communication and setup when the 9plus is used with the 1 1plus V2 Deck Unit e SeatermAF terminal program for easy communication setup and data retrieval when the 9plus is used with the 17plus V2 SEARAM e Seasave V7 program for acquiring converting and displaying real time or archived raw data e SBE Data Processing program for calculation and plotting of conductivity temperature pressure data from auxiliary sensors and derived variables such as salinity and sound velocity Section 2 Description of SBE 9p us Specifications Temperature Conductivity C Sim Pressure A D Inputs 0 to full scale range in meters of Measurement Range 5 to 35 0to7 AUD DOCU aa 0 to 5 volts 6800 10500 meters Initial Accuracy 0 001 0 0003 0 015 of full scale range 0 005 volts 0 018 of 0 001 Typical Stability 0 0002 month 0 0003 month full scale range year volts month influence of 1 ppm total over 20 to 70 C plus 1 ppm first year drift plus 4 additional ye
2. Section 4 Routine Maintenance and Calibration Sensor 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 hie eibi Sea Bird ships the SBE 9plus are supplied fully calibrated with coefficients printed on their sensors back to the user with an respective Calibration Certificates back of manual and stored in the updated configuration xmlcon file instrument configuration xmlcon or con file and Calibration Certificates showing the new coefficients We recommend that the 9plus sensors be returned to Sea Bird for calibration There is no need to send the 9p us main housing along with the temperature and conductivity sensors See TC Duct Disassembly Reassembly below for detailed instructions on removing the sensors Conductivity The SBE 4C 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 geometry resulting in a shift in cell constant Accordingly the most important determinant of long term sensor accuracy is the cleanliness of the cell We recommend that the conductivity sensor be calibrated before and after deployment but particularly when the cell has been exposed to contamination by oil slicks or biological material Temperature The primary source of temperature sensor calibration drift is the aging of the thermistor element Sensor drift will usually be a few thousandths of a degree during the first year and less in subsequent intervals Sensor drift is not substantially dependent on the environmental conditions of use and unlike platinum or copper elements the thermistor is insensitive to shock Pressure The Paroscientific Digiquartz pressure sensor is so stable and immune to environmental effects that much less frequent checks are required Techniques are provided below for making small corrections to the pressure sensor calibration using the s ope and offset calibration coefficient terms by comparing SBE 9plus pressure output to e Readings from a barometer Digiquartz sensors show most of their error as a linear offset from zero Check the 0 pressure reading from the sensor against the local barometric pressure e Readings from a dead weight pressure generator For especially critical work on an annual schedule check the pressure sensor full scale response using a dead weig
