3. Using the lower shoe as a pivot, sweep the
MRP gage back and forth to locate the largest
indicator reading on the part.
Note:
You may want to refer to the MRP
Inspection Tolerance Guidelines at the back
of this manual to determine the accuracy of
the diameter.
4. Rotate the gage 90° and sweep for the largest
reading again.
If your second reading is
greater or less than the first, sweep 180°
around the part to find the largest and smallest
values.
Note:
Be sure that the small revolution counter on
the indicator is pointing to the same number
as when the gage was zeroed. Refer to the
number previously recorded on the back of
the indicator.
