If an MRP gage wobbles or if the wear pads do not sit flush on the surface of a part, it could be an indication that the gage rails are slightly bent. To level the MRP, set the gage on the part and loosen the knobs. Then, turn the rails until both MRP blocks and wear pads sit flush on the part. Re-tighten the knobs and then re-zero the dial using the correct setting standard. If the problem persists, replace the bent rails.
