Tolerances

Alignment quality is evaluated through comparison with tolerances based upon entered
machine dimensions and RPM.

The tolerance ranges are compiled as tables according to type of coupling, coupling format,
and diameter (for the gap value) as well as RPM. When the coupling type is spacer, the tol-
erance table values are determined by the length of the spacer shaft and the RPM.

Tolerances are accessed via the dimensions screen.

Tap the coupling (

1

), then use the carousel that appears to select the desired coupling type

(

2

). Tap 'Tolerances' (

3

) to access the coupling tolerance table.

Available tolerance tables

The available tolerance tables are based on machine operating frequency.
