It's for automotive instrumentation and testing, the most difficult (and hopefully final

) class in the automotive engineering program @ my college.
I think I know what the problem is as far as my numbers go. There's 6 separate scales I could use, and basically the manometer shows percentage of airflow. You then multiply the percentage by what is essentially the "multiplier" for that range. I'm going to calibrate the bench myself or at least *maybe* get something to do it from my buddy @ Tenneco. The flowbench is OLD but it should be working properly. My plan is to try a couple of other ranges on the bench and compare/contrast readings. Then I'll know if the bench is FUBAR'd.
