I was a (pick one) []Calibrator, []Precision Measureing Equipment Specialist
(PME)(PMEL), []Test Equipment dude, []Prima Donna, []Bone Head, when I was
in the Marines for 21 years and nine months. I calibrated all kinds of
stuff that was peculiar and non peculiar to aircraft. Torque wrenches were
in the mix. It was required that we 'exercise' the torque wrenches at least
three times before proceeding with calibration. By 'exercising' I mean
setting the wrench to a high value and turning it until it exceeded the
dialed in value and the head would 'give' indicating that the value had been
reached. The wrench would be off in excess of 10% on the first pull and 5%
on the second and 1% on the third. This applies to all torque wrenches,
dial up values and fixed dials. I have verified these error values by
putting the wrenches on a standard and checking the results. >>
Great information that I was never aware of, Durwood.
