Testing with a small step e.g. in the -10C to 0C dewpoint range will produce even faster results, and allow manufac- turers to make far-fetched claims of response time of 5seconds for a 90% of step change. The cus- tomer has to be aware of these manipulations of data and be able to ascertain the real-world response time they can expect out of a sensor Chilled mirror reference instrument MBW ˚C Appendix H Sample Gas Filter ConsiderationsTested Instrument ˚C 85 -80 -75 -70 -65 -60 -55 -50 -45Sensor Appendix I XDT Grounding ConsiderationsAC Power FacilityAppendix J Analog Output vs. Dewpoint Relationship of 4-20mA output and instrument reading in ppmV or LBS Login Appendix K RS-232C Interface ProtocolHELP command ResetS C K n m BLMeasurement UnitsSPElapsed TimeSPAlarm StatusCRLFBLBLErrorStringCRLF “Error SensOpen” or “Error SensShort” or “Error SensSat”Reset Command “?” commandSerial Number Command Who CommandState User Interface Appendix L Procedure for Exchanging XDT SensorsDewpoint Appendix M Uncertainty in LBS & ppmV calculationsDewpoint Customer Xentaur Return Authorization Number Request FormAppendix M Return Authorization Number Request Form To obtain a RAN fill out this form and fax toPage Index SymbolsPage Page water
