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.
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.
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.
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.
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 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 .
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.
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.
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.
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 C.
