17. Hz C 0 0002 C bit As temperatures and frequencies decrease to typical oceanographic values the sensitivity and resolution increases At 1 C the sensitivity is approximately 48 Hz C System accuracy is determined by the accuracy of the time base used to perform the frequency counting The SBE 25plus uses a TCXO to provide a low jitter higher frequency reference that is stable across the operating temperature range of the instrument This clock is stable to 2 5ppm across 30 to 85 C with a drift of 1ppm per year Auxiliary Voltage Sensor Range Resolution and Accuracy Up to eight voltages with the range 0 to 5 volts DC can be acquired The voltages are selected sequentially by a microcontroller and digitized to 16 bits by successive approximation All eight A D channel voltages are acquired during an interval of approximately 5 milliseconds at the beginning of each scan shortly after measurement of the frequency channels begins Differential input amplifiers followed by 2 pole Butterworth anti aliasing filters are used in each A D channel The A D converter input range of 0 to 5 volts is converted to digital values between 65536 and 0 The resolution at the SBE 25plus A D input ports is therefore 5 volts 65536 0 000076 volts bit Special care is exercised to maintain symmetry between the differential inputs and low pass filters to minimize the influence of temperature gradients encountered in ocean profiling

57. RNING If the SBE 25plus stops working while underwater is unresponsive to commands or shows other signs of flooding or damage carefully secure it away from people until you have determined that abnormal internal pressure does not exist or has been relieved Pressure housings may flood under pressure due to dirty or damaged o rings or other failed seals When a sealed pressure housing floods at great depths and is subsequently raised to the surface water may be trapped at the pressure at which it entered the housing presenting a danger if the housing is opened before relieving the internal pressure Instances of such flooding are rare However a housing that floods at 5000 meters depth holds an internal pressure of more than 7000 psia and has the potential to eject the end cap with lethal force A housing that floods at 50 meters holds an internal pressure of more than 85 psia this force could still cause injury If you suspect the SBE 25plus is flooded point it in a safe direction away from people and loosen 1 end cap bulkhead connector very slowly at least 1 turn This opens an o ring seal under the connector Look for signs of internal pressure hissing or water leak If internal pressure is detected let it bleed off slowly past the connector o ring Then you can safely remove the end cap Physical Handling 1 Rinse the conductivity cell with fresh water See Section 5 Routine Maintenance and Cal

61. Serial Instrument Interface The SBE 25plus can accommodate up to two serial sensors each with individual control sequencing and configuration parameters Each sensor must be compatible with RS 232 signal levels this is a three wire interface consisting of ground TX and RX with I O directions referenced to the instrument connector The two sensors are named Ser and Ser2 These are designated as in the commands described in this section and in the Serial Sensor Setup Command descriptions in Section 4 Deploying and Operating SBE 25plus For example SetEnableSer1 Y enables acquisition of data from Serl SetEnableSer2 Y enables acquisition of data from Ser2 The serial instrument interface is a flexible system that allows data to be collected asynchronously or on demand Data collected from the serial instrument is not interpreted or parsed by the SBE 25plus the 25plus stores the data as part of the instrument data if SetInline Y or in its own file if SetInline N In either case the serial sensor data occupies the same non volatile memory as the 25plus data and counts against the 25plus available memory Configuring a new third party sensor for use on the SBE 25plus is a task made challenging by the multitude of available sensors their unique communication parameters and often sparse documentation The 25plus provides a number of commands for exploring serial instruments With the capabilities in the 25plus new serial instrume
