Provided is a diagnostic apparatus, including a diagnostic unit configured to diagnose a condition of a vortex flowmeter using a determination result of a magnitude of a signal component of each of at least one target detection signal among the at least one detection signal detected by the vortex flowmeter having a vortex generator and a detection unit configured to detect at least one detection signal according to a vortex generated by the vortex generator, or a magnitude of a signal component of at least one of combined signals configured to linearly combine two or more of the at least one detection signal.

Diagnostic apparatus, measurement apparatus, diagnostic method, and computer-readable medium

A transmitter and a method for testing the transmitter which allow easy testing for a failure in the detection processing unit thereof, thereby reducing required manpower and cost, are provided. The transmitter is provided with a detection processing unit for detecting a process variable and processing an electric signal which is based on the process variable. The transmitter is characterized by containing a test unit for generating a malfunctioning state of the detection processing unit for the testing.
