1. A vibration data collection and display system comprising:
a vibration data collection device that monitors vibration of a machine, the vibration data collection device comprising:
a vibration sensor that senses vibration of the machine and generates a vibration signal;
analog-to-digital conversion circuitry that generates original machine vibration waveform data based on the vibration signal, wherein the original machine vibration waveform data include first continuous blocks of data that indicate an occurrence of a vibration event related to a potential fault or performance problem in the machine separated in time by second continuous blocks of data that do not indicate an occurrence of a vibration event related to a potential fault or performance problem in the machine; and
data storage circuitry that removes the second continuous blocks of data, thereby resulting in thinned waveform data comprising the first blocks of data separated in time by blank gaps from which the second continuous blocks of data have been removed, and stores the thinned waveform data;
a data analysis computer that receives the thinned waveform data and executes instructions to generate a thinned waveform plot based on the thinned waveform data, wherein the thinned waveform plot comprises the first blocks of data that are separated in time by gaps representing the second continuous blocks of data that have been removed; and
a display device in communication with the data analysis computer for displaying the thinned waveform plot for viewing by an analyst.
