1. Sample pressure: 5 psig* (* but can be anything that gives you the desired calibration results; the factory calibrates the capillaries for a 5 PSIG sample head pressure. And because sample flow is controlled by a capillary, there is no danger of over pressurizing the reaction chamber. However, excess sample pressure will, at some point, exceed the capabilities of the BPR (back pressure regulator) and control of sample pressure will be nonexistent). NOTE: some customers had a limited sample pressure so the OEM configured many CLDs to run on 2 psig (internal) sample pressure; see below).
2. [opt] Sample pressure: 2 psig* (* but can be anything that gives you the desired calibration results; the factory calibrates the capillaries for a 2 PSIG sample head pressure. And because sample flow is controlled by a capillary, there is no danger of over pressurizing the reaction chamber. However, excess sample pressure will, at some point, exceed the capabilities of the BPR (back pressure regulator) and control of sample pressure will be nonexistent).
3. Sample flow: controlled by sample pressure (mentioned above). The capillary that controls flow to the reaction chamber was sized to either 70cc/min (for high NOX concentrations) or 200cc/min (for low NOX concentrations).
4. Converter temperature: 350°F to 450°F (this is empirically determined by performing a NOX converter efficiency test)
5. Sensor temperature: -1°C to +1°C (check the setpoint value in the Technical menu)
6. Block temperature: 50°C (check the setpoint value in the Technical menu)
7. Bypass flowrate (if the McMillan turbine flowmeter is installed): 400cc/min to 2000 cc/min
