I have a vacuum problem on my agilent 7000 mass spec. I know the rough pump is working as I have switched them over onto our other instrument and the pump is working fine, so I have both pumps working. When I go to pump down the chamber door to the ion source will not vacuum shut. On masshunter, the pump down screen says that the High Vac is off. I have checked connections, I plugged the rough pump into the the wall instead of it getting its electrical supply from the mass spec in case there's a communication error and it is still not working.
Any ideas? please?
