New operation for me

Need to get the Z dim for this part in 8 different places. The hole in the lower left is my X and Y origin. The pin in the front center is my Z origin. I would like to do an auto hit but dont have a clue as how to se that up. Also, I tried to make a plane and a point on the top of the pin but when I set the probe on there the z says .062 I thought that was my Z zero? Help apreciated, customer wants parts, Thanks Bryan
