Calibrating Thread Comparators

Regarding calibration of internal and external thread comparators:

For the Internal Thread Comparator, calibration requires ispecting for wear only. The segment fingers are made as a unit then cut in half. The only element that can be measured is the form of the thread, and the only issue that would make these unusable would be wear on the thread form.

In regards to the Tri-Roll Thread Comparator, the thread measuring rolls are required to spin so this should eliminate the possibility of wear. Recalibration covers evaluating for wear and damage do to misuse and neglect.

It is important to make sure rolls are not locked down during use.

Recalibration covers inspecting both segments and rolls to original manufacturing specifications
