  • Page 5: Introduction

    ANALOX 1371 MK 2 SURVEYOR CARBON DIOXIDE MONITOR INTRODUCTION The ANALOX 1371 SURVEYOR provides a clear Digital Display of Carbon Dioxide concentration in a gas sample. It can be employed either as an ambient monitor, using its internal pump to draw the sample, or as an 'On-Line' monitor if the gas to be checked is flowing through a pipe.

  • Page 8: Installation And Commissioning

    ANALOX 1371 MK 2 SURVEYOR CARBON DIOXIDE MONITOR INSTALLATION AND COMMISSIONING INSTALLATION 3.1.1 The 1371 Surveyor should be mounted on a vertical surface using 3 off M4 machine screws or No. 8 woodscrews. Make sure that the chosen mounting position allows sufficient room on the Left of the Instrument, to permit the hinged front cover to be fully opened, and below the unit to allow cables and pipework to be correctly fitted.

CONNECTIONS 3.2.1 Connections to remote equipment, eg Flashing beacons or High powered Sounders and data recording devices are made through two cable glands, to the screw terminals in the middle area of the terminal compartment.

  • Page 10: Operation

    ANALOX 1371 MK 2 SURVEYOR CARBON DIOXIDE MONITOR OPERATION ALARM SETPOINTS 4.1.1 The Instrument incorporates two completely independent alarm circuits, which may be adjusted by the user, to any point within the full range of the instrument. Both alarm circuits are configured to operate when the measured gas concentration Exceeds the setpoint - ie they are High going alarms.

  • Page 11: Calibration

    ANALOX 1371 MK 2 SURVEYOR CARBON DIOXIDE MONITOR CALIBRATION GENERAL COMMENTS Calibration requires gases to be fed from cylinders of certified concentration. These gases MUST NOT be delivered directly at cylinder pressure to the Instrument, otherwise the internal pump will be damaged. Scottish Anglo E.P. Ltd. supply calibration kits for the 1371 Instrument, comprising two cylinders of gas, a cylinder mounted flowmeter with control valve and suitable tubing.
  • Page 12 ANALOX 1371 MK 2 SURVEYOR CARBON DIOXIDE MONITOR 5.2.4 It is important to realise that the Analyser in this Instrument responds to the partial pressure of Carbon Dioxide in the gas sample and that the calibration is strictly valid only at the temperature and pressure at which the calibration was done.

  • Page 13: Maintenance

    ANALOX 1371 MK 2 SURVEYOR CARBON DIOXIDE MONITOR MAINTENANCE GENERAL Routine maintenance should be carried out at six monthly intervals to ensure continued reliable operation. The procedure detailed below should be followed and should not take more than about 20 minutes. It is strongly recommended that the procedures be carried out by a technician or engineer, familiar with Electronic Instrumentation.

  • Page 14: Principle Of Operation

    The family of Transducers used in the ANALOX 1371 MK 2 range of Instruments are based on a measurement and reference sensor principle, utilising sample path lengths of between 1mm and 100mm in length, depending on the concentration to be measured, and wavelength selection by a carefully specified narrow band interference filter.
