Abstract
Abstract An apparatus for the in-line testing of a transducer including a connector module having a source port, an outlet port, and a test port. The source port is connected to a power source and the outlet port is connected to a transducer. A cap, coupled to the test port, allows for the transmission of power from the power source to the transucer. The transmission of power from the power source to the transducer may be interrupted by removing the cap from the test port. A conventional testing instrument may be connected to the test port for testing or calibration of the transducer once the cap has been removed from the test port.
