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 85 -80 -75 -70 -65 -60 -55 -50 -45 Appendix H Sample Gas Filter ConsiderationsTested Instrument ˚C Chilled mirror reference instrument MBW ˚CFacility Appendix I XDT Grounding ConsiderationsAC Power SensorAppendix J Analog Output vs. Dewpoint Relationship of 4-20mA output and instrument reading in ppmV or LBS Reset Appendix K RS-232C Interface ProtocolHELP command Login“Error SensOpen” or “Error SensShort” or “Error SensSat” BLMeasurement UnitsSPElapsed TimeSPAlarm StatusCRLFBLBLErrorStringCRLF S C K n mWho Command “?” commandSerial Number Command Reset CommandAppendix L Procedure for Exchanging XDT Sensors State User InterfaceDewpoint Appendix M Uncertainty in LBS & ppmV calculationsDewpoint To obtain a RAN fill out this form and fax to Xentaur Return Authorization Number Request FormAppendix M Return Authorization Number Request Form CustomerPage Symbols IndexPage Page water
