Orientation Changed During the Test
The angle of the markings to the Vector changed between the start and end of Measurement.
Changes in orientation can result in an error in the test results.
Considerations
When Measurement ended, the test experienced atleast one of the following cases:
Markings were poorly applied
Clean and reapply markings aligned to the specimen.See Specimen Marking for more information
Specimen was incorrectly mounted in the load train.
Check that the specimen was secured strain within the grips. Poor mounting may introduce movement as load is applied.See Vector not Vertical to Specimen for more information.Load train was incorrectly assembled to the line of load
Check that the grips and fixtures are aligned parallel along the line of load. Poor mounting may introduce movement as load is applied.See Vector not Vertical to Specimen for more information.
Information
Lapped specimens may have caused this warning light, as the markings are at different distances from Vector.
