Before shipment, TAI calibrates the analyzer for your application when feasible. Calibration data is listed in the Appendix. Prior to calibration, TAI checks the electronics of the analyzer and makes all of the necessary internal printed circuit board adjustments. Calibration is performed to determine the proper or close proximity zero and span settings, and also to verify that the analyzer response is linear.
After calibration, TAI makes a lengthy stability check to insure that the analyzer performs within all specifications. We advise that you recalibrate your equipment as part of
1.During shipment, it is possible that components have been jarred out of position or damaged.
2.Your process may be of a proprietary nature. Beyond checking electrical stability, TAI is unable to make a meaningful calibra- tion of the system, requiring these adjustments to be made by you.
3.In other cases precise calibration from the original feasibility/ proposal may have determined field calibration of the analyzer connected to your process stream is required and accuracy will only be obtainable upon representatiive matching and use of the actual process fluid background components at the operating physical conditions of flow, pressure and temperature of the sample.
In any case, it is important that you calibrate the analyzer when it is first installed. Zero checks should be made routinely once or twice a week and span calibration should be performed weekly, at first, and monthly after reproducibility is assured.
