I want to use a Varian 979 as a pumping station to pump-clean a cold head. The cold head was filled with pure He4, so the leak rate would overload. Can I turn off the filament of the mass spectrometer to prevent overloading?
You cannot turn the filament off
We do not have any resources for Varian 979 leak detector. I will see if we have a resource for this question
This is the answer I received from the vacuum division:
It won’t hurt the machine to use it as a pump, but why not just use theroughing pump alone without the leak detector? It would pump much fasterdirectly attached.
You can contact them directly 800 882-7426, option 3
The filament on that model cannot be turned off.
