main valve on vac chamber closed, turbo still running (just in case)
ion pump current: 7.3mA
ion pump voltage: 720V
tried to add voltage/current monitor signals to DAQ but analog outputs seem to be broken.
voltage monitor should be 1V/kV but is about 12V
current monitor is railing at 15V as it might only work in low current regime. Manual is wrong, does say signal should be 1V/kV , so don't know what i should expect>
But ususally mA are too much so i expect it to work below 1mA.
