problem with frick screw volume

[Grizzly]

Sorry for taking so long to post. While i was on vacation another tech went to look at problem.He found that i was trying to calibrate slide valve and volume at high load conditions and high compression ratio that was causing calibrating problem. He shut off most of the load and re-calibrated slide and volume, compressor volume is now functioning properly.Lesson learned never try to calibrate at high load conditions, never though of that, hats off to my coworker, thanks Jason.

Sam.
In my opinion it takes a mature engineer to admit when He is wrong!

You have and fair play to you.
I applaude you!
(After all if you are not making mistakes, you probaly arn't doing anything?)
