MODEL 300 COMBUSTION ANALYZER1-2 Instruction 24-92231.2 BASIC FEATURESThree large LED readouts display the following information about boththe combustion process being analyzed, and the instrument itself:• O 2 Cell Output (mV) • CO Level in ppm • % Loss• Analyzer Errors • % Efficiency • % O 2• Stack Temperature (°F /°C) • % Excess Air • % CO2Because the Model 300 Combustion Analyzer is a “smart” instrument, itsoperation is fast and virtually mistake-proof. Programmed routines leadthe operator through the proper sequence of start-up and test procedures,signaling what action is required, and locking the instrument into awaiting mode until the proper action is taken.The instrument’s microprocessor is programmed to compute percentefficiency, percent excess air, and percent carbon dioxide for the sevenfuels described in Table 2 (in the front of this manual).In addition to the instrument’s microprocessor control and displaycircuitry, the following items are also provided with each Model 300Combustion Analyzer inside its suitcase style carrying case:• Particulate trap wrench.• AC power supply, or battery pack with charger.• Air-filter/water-trap with three replacement filters.• Optional printer with one extra roll of paper.• Instruction manual.• O 2 and CO sensor.• On analyzers supplied with a probe and hose:· 11 inch rigid probe with integrated particulate trap (optionalextended-length, high-temperature probes are also available).· 22 feet of hose and thermocouple wire (optional extended lengthsof hose and thermocouple wire are also available).
