Zeroing the MRP Gage for Internal Measurements Using the MIC TRAC

Materials Needed:



MRP gage



MIC TRAC MIC TRAC, CPU, and taper blocks



5/32” hex wrench (supplied with gage)



Cloth

To ensure consistent and accurate readings, the MRP gage should be zeroed on the MIC TRAC

once during each shift, at a minimum.

1. Turn on the MIC TRAC CPU.

2. Clean both of the receiver pads and the

mounting surfaces of the taper blocks using a

cloth.

3. Place the taper block against the receiver pad

shoulder with the raised side of the block

facing outward.

4. While holding the block against the receiver

pad shoulder, insert the two cap screws with

washers into the holes on either side of the

block.

5. While applying pressure toward the receiver

pad shoulder, use a 5/32" hex wrench to

tighten the screws.

6. Repeat this process with other taper block.

Raised Side of

Block
