I was able to do that too...while I was waiting in the car for my wife
outside the Goodwill store. Got a little better evacuation however; I kept
the engine running while the vacuum pump was working. My transconductance
measurement was also slightly more linear. Still...he doesn't do a bad job
for an amateur.
