
] key to move to the “Vibration” field. The “Vibration” field determines the
engineering units in which the amplitude, or “Y” axis, of the spectra will be displayed.
Consult the appropriate equipment maintenance manual for specific requirements of a
vibration survey or for analysis guidelines. Use the [

] or [

] keys to scroll through the
selections in this field. The available selections are: IPS (Inches Per Second), mm/sec
(millimeters per second), cm/sec (centimeters per second), mils (1/1000th of an inch),
microns (1/1000000th of a meter), m/s/s (meters per second squared), and cm/s/s
(centimeters per second squared).
