J 38792-A Electronic Vibration Analyzer

The J 38792-A, electronic vibration analyzer (EVA), is a 12-volt powered hand-held device, similar to a scan tool, which receives input from an attached vibration sensor or accelerometer and displays the most dominant input frequencies (up to three) on its liquid crystal display. The vibration concern frequencies are obtained through the use of the J 38792-A while following the Vibration Analysis Diagnostic Tables. The frequencies obtained, when applied to the Vibration Analysis Diagnostic Tables, are used as a primary input to help determine the source of the vibration concern.
