311XL SERIES TRACE OXYGEN ANALYZER 1. INTRODUCTION 1.1 Description : The Teledyne Analytical Instruments (TAI) Model 311XL and 311TCXL are portable, intrinsically safe trace oxygen analyzer which can be operated without an external power source. These analyzers w ill be referred to as Model 311XL or 311XL Series analyzers in this manual.
1.3.2 Reliable Calibration . Although this instrument can be calibrated with air, the use of a calibration gas gives better results on the lower PPM ranges.
A current limiting resistor (R1 and R2) is potted into the end of each battery. This assures that under no circumstances can more than 25 m illiamp eres (100 m illiwatts) be switched or drawn from either battery supply. This means that the Model 311XL m ay be used in explosive atmospheres where arcs of 100 milliwatts or less can be tolerated.
2. SUPPORTING EQUIPMENT AND SERVICES 2.1 Sampling Equipment . The customer must provide a m eans of controlling the pressure and flowrate of the sample gas. For positive pressure applications, TAI suggests a simple throttle valve installed in the sample line between the sample point and the analyzer.
3.1 Introduction . The Model 311XL is supplied completely assembled and ready for instant use. The Micro-Fuel Cell must be installed prior use. When a sensor is first installed, the instrument should be purged for 12-16 hours with zero gas (an inert gas such as nitrogen or argon with less than 0.
Span gas: An inert gas (nitrogen or argon) with a known trace amount of oxygen. The oxygen content should be 70 – 90% of the full scale on the range of interest (working or primary range).
2) Establish a flowrate in the sample line of from 0.2 to 5 liters/m in. Allow the sample to flow long enough to allow a stable low reading to be achieved. When disconnecting the instrument, reverse the procedure: source f itting first, and then vent fitting.
that an overnight recharge be accomplished ev ery three (3) weeks of continuous use. To recharge the batteries, place the range switch in the “OFF” position and connect the power cord to a convenient outlet. NOTE: The amber charge lamp (on the rear of the case) will be lit during charging process.
The spare cell should be carefully stored in an ar ea that is not subject to large variations in ambient temperature (75 Deg. F nom inal), and in such a way as to obviate any possibility of damage. Under no circumstances, disturb the integr ity of the cell package until the cell is to be actually used.
5. TRANSDUCER AND TEMPERATURE COMPENSATION The Micro-Fuel Cell has an inherent positive temper ature coeff icient, the effects of which have been minimized through the im plementation of a thermistor com pensation circuit. Internal electronic calibration is accomplished by TAI.
