Abstract

A measurement equipment monitoring system (30) includes a shaft centerline offset measurement device (40) and a shaft height measurment device (50) connected by electrical conduits (EC) to a control/display console (60). Console (60) includes a handle (60A) for portability, a keypad (60B), a printer (60E) and an on-board dot matrix display screen (60C) for displaying measurement results. Alternatively such can be sent externally through a communication port (60D).
