Introduction1.2 Displayed DataPCAThe PCA directly measures, displays, and stores the following data:• Room Temperature in °F or °C (Primary Air/Ambient Temperature)• Flue Gas Oxygen Content in %• Flue Gas Temperature in °F or °C• Flue Gas Carbon Monoxide Content (H2 Compensated) in ppm(For analyzers having a Carbon Monoxide sensor)• Flue Gas Nitric Oxide content in ppm(For analyzers having a Nitric Oxide sensor)• Pressure/Draft in Millibars, Pascals, or Inches of Water Column(For analyzers having a draft sensor)• Differential Pressure in Millibars, Pascals, or Inches of Water Column(For analyzers having a draft sensor)The PCA will compute, display, and store the following data for any of theseven standard fuels:• Combustion Efficiency in %• Excess Air in %• Flue Gas Carbon Dioxide Content in %• Flue Gas Carbon Monoxide Content referenced to Oxygen in ppm(For analyzers having a Carbon Monoxide sensor)• Flue Gas Nitric Oxide Content referenced to Oxygen in ppm(For analyzers having a Nitric Oxide sensor)The seven standard types of fuels that can be selected are:• Natural Gas• Oil #2• Oil #4• Oil #6• Kerosene• Propane• CoalThe PCA continuously monitors flue gas exhaust conditions and updatesthe above displayed values during a combustion test. If the analyzer isequipped with an optional pressure sensor, then draft measurements canbe made simultaneously with the combustion test, or made separately.The analyzer has the capability of storing data that was collected duringa combustion test or draft measurement. The stored data can then at alater date be either viewed on the PCA’s display, printed using an op-tional printer, or downloaded to a computer.1-2 Instruction 0024-9219
