Shaft Center Line (SCL)
Shaft Centerline (SCL) is used to display the change in gap voltage for a Channel Pair. SCL is typically
used in conjunction with Displacement Probes.
In order to get valid SCL displays the input channels must be DC coupled.
The measured DC Gap Voltage is corrected to the Gap Reference Value and Shaft Starting Location
(Brg Start), which are set in the Edit pull-down menu’s Setup Configuration window, in the Input
Channels tab.

ECCENTRICITY (e)
Note: Eccentricity “(e)” is computed and displayed as a cursor value for Shaft Centerline plots.
Eccentricity is the ratio of current gap to the bearing clearance.
