when testing with a dial gauge, the FSM is missing a few points.

You need to use some small bolts with the same thread as the lug bolts so the rotor sits tight against the hub, if you leave it loose and adjust the clearance, you will end up wrong as the rotor can flop a bit. Unless you are mounting the foot of the magnetic base on the hub.

Another point is to unload the brake caliper first (if the brakes are assembled)
