If I recall (been a while since I've seen this thread and I *THINK* I
started it)...
runout would be measured against the outside rim of the platter, thus
checking for a platter that is mounted off-center.
flatness would be measured against the outer top surface of the platter,
thus checking for a platter that is mounted "at an angle".

Subject: Runout vs. Flatness and Dial test indicators
just would like to enquire..
Is the DTI reading for run-out the difference between the high and low
limits or is
it the average of the difference
