Abstract
A hand-held apparatus gathers and analyzes test data associated with rotating electric machines, where the test data is indicative of one or more operational characteristics of the mechanical equipment. The apparatus, which is operable to be carried by an operator from one machine to another along a test route, includes a sensor input port for receiving a sensor signal from a sensor, where the sensor signal is indicative of one or more operational characteristics of the rotating electric machines. The apparatus also includes a signal conditioning circuit for receiving the sensor signal, and for conditioning the sensor signal to produce a conditioned signal which is appropriate in format to be digitally processed. A processor, which is coupled to the signal conditioner, receives and processes the conditioned signal according to processing instructions and processing parameters to produce a test spectrum. The processing parameters determine one or more characteristics of the test spectrum. A memory device, which is coupled to the processor, stores a plurality of executable test expert modules, each containing the processing instructions for processing the conditioned signal in a particular way to determine one or more of the operational characteristics of the rotating electric machines. An operator input device is coupled to the processor for receiving input from the operator to select one of the test expert modules to be executed to process the conditioned signal according to the processing instructions contained in the selected module. The apparatus further includes a display device for displaying the test spectrum to the operator. The test expert modules contain processing instructions for determining whether the processing parameters have been set according to a predetermined configuration for a particular test point on the test route, and for processing the conditioned signal in a way dependent upon whether or not the processing parameters have been set according to such a predetermined configuration.
