2 questions regarding vacuum pump
(OP)
First im having an issue with my manometer. I have a controlled leak valve on my rotary vacuum pump setup to controll how much vacuum it pulls. By logic as i close the valve my manometer should read lower torr, but instead it goes up. My manometer has a positive and negative pressure connection like the one in this picture http://cfnewsads.thomasnet.com/images/large/583/58... . But the manual that came with mine did not say which was positive and which was negative so i tried to get readings with both sides but each side had the same issue, and the vacuum increased the torr increased which shouldnt happen.
The second question is a quick one, can i leave clean vacuum oil in the pump?
