Declared indicator-record screen
Profile / runout variation
Inputs
Choose the record label only; this workspace does not construct a profile or runout tolerance zone.
Lowest reading from the one documented fixture/datum setup; signed readings are allowed.
Highest reading from the same documented fixture/datum setup.
Tolerance copied from the applicable controlled requirement; this is not a drawing-parser field.

observed variation = rmax − rmin; ratio = observed variation / stated tolerance

Method
Formula, when it applies, and when it does not
Subtract entered high and low indicator readings for a profile, circular-runout, or total-runout record and compare the observed variation to a tolerance.
observed variation = rmax − rmin; ratio = observed variation / stated tolerance
When
- Declared control type
- User-established datum/fixture
- Comparable readings
- Observed extrema only
Don’t
- This is extrema subtraction for a user-declared circularRunout record. It does not establish a datum axis, construct profile or runout zones, parse feature-control frames, select fixture/CMM/indicator strategy, assess measurement uncertainty, determine conformance, or certify drawing compliance.
