J 38792-A  Electronic Vibration Analyzer. See Special Tools .

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 dominate input frequency(ies) (up to three) on its liquid crystal display. The vibration concern frequency(ies) are obtained through the use of the J 38792-A  while following the Vibration Analysis Diagnostic Tables. See Special Tools . The frequency(ies) obtained, when applied to the Vibration Analysis Diagnostic Tables, are used as a primary input to help determine the source of the vibration concern.
