Subject:      AFM test readings
Content-Type: text/plain; charset=UTF-8

Thanks to Jarrett Kupcinski, I have acquired a spare AFM and am attempting
to understand the testing as detailed in Bentley on page 24.57

Since I now have a spare to work with, I have compared the measurements
between 3 & 4 and 1 & 4 between the original and spare and receive
essentially the same readings.

My question concerns the measurement between terminals 2 & 3  --- Bentley
says the value should be a resistance change when the air sensor flap is
moved

But, does it matter what the range of change looks like?  It it starts out
as .55 but changes to a high of 1.5 somewhere along the movement of the
flap, is that better than a high value of 1.2 or even a high value of .6
since any of those would provide a resistance change.

Or, should I be looking at values when the flap is fully opened?  Or should
I be looking for some other variance?

Thanks for helping me understand this.
