    ALPHA OMEGA INSTRUMENTS CORP. SERIES 9510 CARBON DIOXIDE ANALYZER INSTRUCTION MANUAL 3.3.3 Fail Safe Switches #1 through #4 control the fail-safe operation for each of the four alarm relays. Each switch must be turned "ON" to be fail-safe (refer to FIGURE 3.0). In the fail-safe mode, the normal or non-alarm state of each of the four (4) alarm relays is energized.

  • Page 23: Timing Out During Setting

    2 pounds per square inch (PSI). If the pressure is expected to be in excess of 2 psi, it is advisable to use a pressure regulator (Alpha Omega Instruments Model Number 9PRR or 9LPR). Flow rates through the analyzer should be between 100 to 300 milliliters per minute (ml/min.) for precent systems and approximately 150 millimeters a minute for trace systems.

  • Page 24: Calibration Procedures

    The frequency of these checks is often determined by in-house calibration protocols. If none exists, Alpha Omega Instruments Corp. recommends that a calibration check be made on an average of once every 6 months.

  • Page 25: Procedure For Checking Calibration With An Open Diffuser System

    ALPHA OMEGA INSTRUMENTS CORP. SERIES 9510 CARBON DIOXIDE ANALYZER INSTRUCTION MANUAL Note: calibration gas flowing through the carbon dioxide sensor is discharged inside the analyzer enclosure. Therefore, it is imperative that no combustible gases i.e. methane, hydrogen, etc. be used for calibration.
