Ive tried can seem to find any manuals online for one like mine.If its reading gage pressure could i not just subtract the reading from atmospheric to get the absolute pressure?
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...
