6-1 INTRODUCTION. This chapter provides corrective maintenance procedures for the transducer. These
procedures include testing, cleaning, inspection, adjustment, and final checkout. Corrective maintenance should be
performed as a result of improper performance during operation or malfunctions that may occur during testing and
troubleshooting procedures.
6-2 SPECIAL TOOLS AND TEST EQUIPMENT. The required special tools and test equipment for testing
and corrective maintenance of the transducer are
a)
Approved Calibration System
b)
Approved Adjustable Pressure Source
6-3 PERFORMANCE TEST. Performance testing of the pressure or differential pressure transducer is limited
to checking and adjusting the transducer calibration.
6-3.1 TEST CONDITIONS. All performance tests shall be performed at room ambient conditions (20°C,
atmospheric pressure).
6-3.2 CALIBRATION CHECK AND ADJUSTMENT. Check and adjust calibration of the transducer as
follows:
For detailed information regarding calibration system setup, operation, and related
precautions, refer to the technical manual applicable to the calibration system in use.
a) Select an approved calibration system in accordance with the range and output option of the transducer
being calibrated.
Observe all precautions given in the calibration technical manual and in Navy
precautions for forces afloat OPNAVINST 5100.
Air or nitrogen under pressure is used in the operation of the pressure transducer
calibration system. Severe injury may result if personnel fail to observe safety
precautions.
To prevent injury, insure all connections are properly made before applying air or
