1. INTRODUCTION 1.1 Description : The Teledyne Analytical Instruments (TAI) Model 311-D is a portable trace oxygen analyzer which can be opera ted without an external power source, and reliably calibrated without the use of cumbersome, questionable, “certified” calibration gases. The instrument provides for trace oxygen analysis in decade steps[...]

After the electronics have been properly zeroed (a one-time factory operation), the instrum ent cannot produce an output indication in the absen ce of oxygen; therefore, the need for a “zero” standardization gas is obviated. 1.3.3 Integral Power Supply : The differential power and digital panel meter (DPM) requirements of the inst rument am pli[...]

Further disassembly may be accom plished by rem oving the backplate assemb ly from its four mounting standoffs, and laying the two separated assem blies out as illustrated on the “Analyzer Wiring Diagram”. The diagram is included among the drawings at the rear of the manual. 1.3.6 Circuit Description : A Micro-Fuel Cell (Class B-2C) is used as [...]

necessary or desirable, it must have a metallic diaphragm. Regulators with organic or plastic diaphragms are permeable to oxygen, and if used in the sampling system, will lead to high oxygen readings. For atmospheric pressure sampling, connect a pum p and flow control valve downstream from the analyzer and draw (rather than push) the sample through[...]

dictated by the customer’s application. If the instrument were being used to certify the oxygen content of a product for delivery, then a calibrati on prior to certification would certainly be in order. If, on the other hand, the instrument is being used to monitor or guard a sam ple, the evidence provided by the analyzer will determine when a ca[...]

If, on the other hand, the instrument is not to be used imm ediately after calibration, and a low ppm oxygen gas is being employed as a purge, allo w the m anifold to be purged overnight, and then disconnect both male fittings. ALWAYS DISCONNECT THE SOURCE FITTING FIRST, AND IMMEDIATELY THEREAFTER, THE VENT FITTING . 3.3 Positive Pressure Sampling [...]

every two (2) days of continuous use. To rech arge the batteries, place the range switch in the “OFF” position and connect the power cord to a convenience outlet. The integral charging circuit will automatically energize and regulate batte ry charging current when the switch is in the “OFF” position and the AC cord is plugged into the power[...]

No tools are required to replace the cell in the in strument. Sim ply unscrew (ccw) the plug at the bottom of the analyzer, and the cell will drop out of the m anifold cavity. Remove the new cell from its package, and carefu lly rem ove the shorting clip. Do not touch the silver-colored sensing surface of the cell -- as it is covered with a delicat[...]

1. Disconnect cell. 2. Move range switch to “CAL” position. 3. Adjust P1 such that the output of A3, pin 6, measures between 0 and +0.5 mV, ideally +-.3 mV. 4. Adjust P2 for 0 ± 1 mV at output of A2, pin 6. 5. Verify that the offset is the same on all ranges. 6. Re-connect cell. 6. LEAK TESTING If a leak is suspected in the unit, DO NOT ATTEMP[...]

OPERATING TEMPERATURE RANGE: 30 ° TO 125 ° F. RESPONSE AND RECOVERY: AT THE SPECIFIED FLOWRATE (0.25 SCFH), THE SENSOR OUTPUT SHOULD BE, IN TEN SECONDS, WITHIN ± 10% OF AN INTRODUCED GAS HAVING A CONCENTRATION OF 100 PPM OR MORE; FOR A CONCENTRATION OF LESS THAN 100 PPM, THE SENSOR OUTPUT SHOULD BE WITHIN ± 10% IN SIXTY SECONDS (PROVIDED THAT T[...]
