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 Tested Instrument ˚C Appendix H Sample Gas Filter Considerations85 -80 -75 -70 -65 -60 -55 -50 -45 Chilled mirror reference instrument MBW ˚CAC Power Appendix I XDT Grounding ConsiderationsFacility SensorAppendix J Analog Output vs. Dewpoint Relationship of 4-20mA output and instrument reading in ppmV or LBS HELP command Appendix K RS-232C Interface ProtocolReset LoginBLBLErrorStringCRLF BLMeasurement UnitsSPElapsed TimeSPAlarm StatusCRLF“Error SensOpen” or “Error SensShort” or “Error SensSat” S C K n mSerial Number Command “?” commandWho Command Reset CommandState User Interface Appendix L Procedure for Exchanging XDT SensorsAppendix M Uncertainty in LBS & ppmV calculations DewpointDewpoint Appendix M Return Authorization Number Request Form Xentaur Return Authorization Number Request FormTo obtain a RAN fill out this form and fax to CustomerPage Index SymbolsPage Page water
