Thanks to everyone who provided information on how to do the test.  Like a
lot things, once you learn how to do something, it is not really hard or
complicated.

Using information from Neil, Karl, David and others the test was pretty
simple.  I ended up testing my existing AFM, the new one Jarrett helped me
acquire, and a spare that a friend has.  All three passed with flying
colors and the analog meter needle moved smoothly on all three.  Before
testing, I took the time to clean all three with CRC Mass Air Flow Sensor
Cleaner.  The inside body of mine with 160K miles was pretty clean already
but the one my friend had was terribly gunked up but sparkles now.

Since I learn visually, the video at this link also helped:
