Using the NT VARIO pump as fore-vacuum pump (also known as a

”roughing pump” or ”backing pump”) for a high vacuum pump (e.g. turbo-

molecular with high fore-vacuum tolerance):

Use ”Pump down” function with ”

Speed

” set to ”HI” or

Use ”Vac control” function with ”

Set vacuum

” set to ”Turbo”.
