4040 - Methane / Nonmethane analyzer - Teledyne Analytical ...

OperationOperation4.1 Analyzer OperationAlthough the Model 4040 has been programmed for your applicationat the factory, it can be further configured at the operator level.Depending on the specifics of the application, this might include all or aset of the following procedures:1. Setting system parameters• Establish a security password, if desired, requiring operatorto log in• Establish and start an automatic calibration cycle• Choose autoranging or select a fixed range of analysis• Set alarm setpoints and modes of alarm operation• Calibrate analog output, select analog output source.2. Routine operation• Calibrate the instrumentProcedures for accessing and/or changing parameters as well asanalyzer operation are detailed in the sections to follow. In general, thesequence of menus available on screen follows a logical course for setupand operation. It is not required, however to follow this sequential path.The user could, for instance, go directly to set an analysis range and thenprogram an offset to the current output for matching a range on theuser’s recording device. The only exception to this is when theinstrument is powered up. It will go through a warm-up period, followedby a diagnostic self-test routine.Note: The 4040 is always either analyzing or in a span calibration.The analysis has 2 phases, the CH4 phase and the NMH phase,as does the span calibration. For a detailed description ofthese phases, please refer to THEORY OF OPERATION.Teledyne Analytical Instruments 43
