Dyno operators advice needed. When we have our engines dynoed how do we know the dyno is calibrated/setup right? Looking at the instrumentation on the dyno is there a certain gauge or gauges we can look at to make sure our dyno results will be accurate? We hear a lot of talk about "Happy Dynos" we even have a post on here referring to "Happy Dynos" I did not want to hijack that post with this question.

Hopefully some of you dyno gurus can step in and tell us the correct procedures for setting up the dyno.
