Zeroing the MRP Gage for Internal Measurements Using the MIC TRAC
19. Using a scale, adjust both arms to the proper
MIC TRAC setting dimension.
20. Tighten the set screws on the side of the upper
and lower blocks with a hex wrench to secure
the arms.
21. Place the MRP gage on the MIC TRAC so the
pivot shoes are positioned on the inside of the
taper blocks.
22. With the pivot shoe of the upper arm contacting
the taper block, slide the entire MRP gage
toward the upper block approximately .050”.
Then, slide the lower block back until it
contacts the right taper block, to give the MRP
the proper preload.
