A portable static-pressure calibration instrument for use with the LLL telemetry transducer system at the Nevada Test Site (NTS) is described. It is significantly more accurate and rugged than the bourdon-tube pressure guage it replaces, and can be incorporated into a field-use, semiautomatic, pressure calibration system. The process by which a transducer is selected for EPMT use from the inventory of field-service-certified transducers and subjected to an extensive preconditioning and calibration procedure is described. By combining this unusual calibration procedure with a unique, statistically based data-reduction routine, the total uncertainty of the measuring process at each calibration point can be determined with high accuracy.
