  • Page 61: Functional Description

    Section 10 Model 650 Noxygen Analyzer Functional Description 10.1. Operating Principle- NO/NO The California Analytical Model 650 Analyzer utilizes the chemiluminescent method determination of oxides of nitrogen (NO or NO ) in a sample gas. In the NO mode, the NO in the sample is quantitatively converted to NO by gas phase oxidation with molecular ozone produced by the UV reaction of cylinder air.

  • Page 62: 10.2. Principle Of Operation-Oxygen

    Section 10 Model 650 Noxygen Analyzer 10.2. Principle of Operation-Oxygen The paramagnetic susceptibility of oxygen is significantly greater than that of other common gases, and consequently, the molecules of oxygen are attracted much more strongly by a magnetic field than the molecules of the other gases. Most of the other gases are slightly diamagnetic, which means that their molecules are then repelled by a magnetic field.

  • Page 63: Figure 10-3 Principle Of Operation

    Section 10 Model 650 Noxygen Analyzer amplifier, which in turn is fed to the feedback coil of the measuring cell. If the oxygen content of the gas sample changes, the corresponding current output of the amplifier, which is proportional to the oxygen content, produces a magnetic field in the feedback coil opposing the forces and thereby causing the dumbbell to rotate.

  • Page 64: Cross Sensitivity Of Gases

    Section 10 Model 650 Noxygen Analyzer 10.3. Cross sensitivity of gases The very high magnetic susceptibility of oxygen is the basis of the paramagnetic measuring principle. In comparison to oxygen, other gases have such a minor susceptibility that most of them are insignificant.

  • Page 88 ADDENDUM 13.5 Starting With SERIAL NUMBER UO6081 1.0 INTRODUCTION The Model 600 CLD Series Instruments starting with Serial Number U06081 have several new Hardware and Software features. The Hardware includes the use of a new memory system, isolation of the analog output signals and 15 relays that are used to buffer the many new digital output signals that are now available.
  • Page 89 ADDENDUM 2.0 OPERATION OF MEASUREMENT KEYS Note: The  & Keys continue to be used to view a complete list of menu items. 2.1 Over Range 888888 In the MEASUREMENT mode only, any value that exceeds the “range” by more than10% will be displayed as 888888. 2.2 Diagnostics: Use F3 to toggle between MEASUREMENT and DIAGNOSTIC.
  • Page 90 ADDENDUM 2.4 Span: From the MEASUREMENT Screen select the required range then press F6. Note: For instruments with an Internal Span Solenoid select Calibration by Valves. (Main, F5, F2, F4) 2 versions Span Gas will be enabled and the observed results can be used to evaluate instrument performance.
  • Page 91 ADDENDUM 2.5 Range Limits: F8 From the MEASUREMENT Screen; 2 versions The standard analyzer is factory configured with 4 Physical Ranges of 3, 30, 300, 3,000 PPM. The optional high level analyzer is factory configured with 4 Physical Ranges of 5, 50, 500, 500 The operator can change the number of ranges and select a more convenient full scale concentration if required.
  • Page 92 ADDENDUM 2.7 Outputs: F10 From the MEASUREMENT Screen Use the ↕ to select the desired Output. Press Enter to select Use the ↕ to select the desired Signal. Press Enter to select Use this screen to define the signals and their location that will be monitored by a remote reordering device.
  • Page 93 ADDENDUM 3.0 NEW FUNCTIONS 3.1 Auto Start Up: (Main, F5, F7, F7) All key analyzer parameters are stored in a secure memory location and retained when power is removed In the event of an unexpected power failure it may be desirable to change some parameters until an operator can resume control.
  • Page 94 ADDENDUM 3.2 Alarms On/Off: (Main, F5, F7) All key analyzer parameters are stored in a secure memory location and retained when power is removed. In the event of an unexpected power failure it may be desirable to change some parameters until an operator can resume control. This screen may be used to establish several desirable special instrument start-up parameters that define how the analyzer recovers from loss of AC power.
  • Page 95 ADDENDUM 3.3 Offset & Gain: (Main, F4, F3, F5) This screen can be used to provide an additional means to display calibration deviations. The OFFSET is the value stored during zero calibration. The GAIN is the value stored during span gas calibration using the operator defined calibration gas.
  • Page 96 ADDENDUM The D-A CALIBRATION screen will then be used to complete the calibration procedure. This screen provides a section that is used to record the zero signal corrections (zero offset) and a second area to record the 100% signal corrections (Gain) for each of the four output signals that may be defined to develop a voltage or current signal.
  • Page 97 ADDENDUM Procedure 3.4.1 From the Main Menu press F5,F7,F3, to obtain following screen: 3.4.2. Use the ↕ to highlight the outputs that require calibration. 3.4.3. Press enter so you provide access to all the menu of signals that are available. (Real Time, N0, N0x, Calibration, Sample Pressure, etc.) 3.4.4.
  • Page 98 ADDENDUM 3.4.5. Press BACK to return to the SYSTEM SETUP screen (Main,F5, F7) 3.4.6. Press F8 to obtain the following screen Main, F5, F7, F8 3.4.7. Use the ↕ to select the desired output press ENTER. 3.4.8. Press F1 to select a ZERO signal and observe the results on the remote device 3.4.9.
