[T3] An idea for calibrating the manifold pressure sensor.

["Mark Healey" <marksvw@healeyonline.com>]

Today I found a virgin manifold pressure sensor (I guess the epoxy
seal is the hymen).  I'm thinking that before I put it in I could use
it as a comparison for calibrating the old one.

>From what I understand it is just a variable transformer.  Lacking an
o-scope and sig. gen., I figured that I could use an unrectified
transformer I have from an old dustbuster which puts out 13v.  I would
hook that up to one side of the new one and measure the AC voltage
from the other side with my multimeter.  I then would transfer the
transformer and meter to the old one and adjust until I got the same
reading.

It's been a long time since I've done any analog electronics so I
might be insane on this one.  Am I?
