  • Page 5: Introduction

    Introduction 1 Introduction Description The Teledyneg Analytical Instruments (TAI) Model 311PC is a por- table, intrinsically safe percent oxygen analyzer which can be operated without an external power source and reliably calibrated without the use of cumbersome, questionable, so-called “certified” calibration gases.

  • Page 6: Outstanding Features

    1 Introduction Model 311PC Outstanding Features The following unique features are incorporated into the Model 311PC: • Micro-Fuel Cell The Micro-fuel Cell (U.S. Pat. Nos. 3,767,552 and 3,668,101) is a sealed electrochemical transducer with no electrolyte to change or electrodes to clean. When the cell reaches the end of its useful life, it is merely thrown away and replaced, as one would replace a worn out battery in a flashlight.
  • Page 7 Only when the selector switch is placed in the OFF position will the neon lamp on the back plate of the Model 311PC light up to indicate power to the battery charging circuit.
  • Page 8 1 Introduction Model 311PC • Compact Packaging The instrument is housed in 6- X 9- X 5- in aluminum case that is equipped with a carrying handle and foot pads. When in use, the analyzer should be placed in an upright position on a level surface (off level positioning will detract from meter accuracy).

  • Page 9: Installation

    ¼ ampere of current will be periodically re- quired to recharge the instrument’s battery power supply. An internationally approved 3 wire detachable power cord is provided with the instrument and should be stored in a safe place when not in use. Teledyne Analytical Instruments...

  • Page 11: Operation

    Operation 3 Operation Introduction The Model 311PC is supplied completely assembled and ready for instant use. The Micro-fuel Cell is packaged separately and should be installed prior to use (see Section 3.2). The integral shut-off valves in the quick disconnect sample fittings, if not disturbed, will provide a seal from oxygen in the air and extend the life of the Micro-Fuel cell when the instru- ment is not used for extended periods of time (week—months).

  • Page 12: Positive Pressure Sampling

    3 Operation Model 311PC Positive Pressure Sampling When connecting the instrument to a positive pressure sample source, always proceed as follows: 1) Before making any connections to the instrument, establish a flowrate in the sample line of from 0.1–10 liters/min using a throttle valve between the positive pressure source and the instrument inlet (1–2 liters/min is suggested).

  • Page 13: Calibration

    TAI feels that the interval between calibrations should be dictated by the customer’s application. The Model 311PC should be calibrated using a span gas with a known oxygen concentration. Ambient air (20.9% ) is recommended for calibra- tion.

  • Page 14: Calibration Procedure Using Calibration Gas

    3 Operation Model 311PC 3) Install the plastic tube equipped male disconnect fitting in either of the analyzer’s sample ports, and a blank disconnect fitting in the other port (direction of sample flow is of no importance). A pump is recommended on the plastic tube. Pump the tube until the meter reading is stable.
  • Page 15 5) Immediately after step 4 has been accomplished, disconnect the calibration source gas fitting at the analyzer sample port, and plug in either the sample or a source of zero gas. Always disconnect the source fitting first, immediately followed by the vent fitting. 3–5 Teledyne Analytical Instruments...

  • Page 17: Maintenance

    Maintenance Battery Power Supply Service The Model 311PC is designed to be intrinsically safe, and therefore is for use only when it is not connected to the AC power line. TAI suggest that an overnight recharge be accomplished every four (4) weeks of con- tinuous use.

  • Page 18: Routine Maintenance

    4 Maintenance Model 311PC Routine Maintenance Beyond adhering to a battery recharge schedule, no routine mainte- nance is required, as there are no moving parts in the instrument other than the meter movement. The Micro-fuel Cell is a sealed, modular component that should be replaced only when faulty.

  • Page 19: Cell Warranty

    Cell Warranty The Class B-1 cell employed in the Model 311PC is warranted for six (6) months of service. With regard to spare cells, service time starts when the cell is removed from its shipping package.
