    Description

    Used Varian Turbo-V 70 with controller unit and cable.  The pump and controller were tested, and work.
    Unit tested as follows:
    1) Connected a regular vacuum pump to the turbomolecular pump. Pumped air out of turbomolecular pump to get vacuum inside..
    2) Hooked up controller.  Shorted interlock pins 3&8 on P1 connector per manual (

    )
    3) Shorted pins 1&6 to start pump.  Monitored pump with stethoscope.
    4) Verified by sound that pump ramped up to intermediate speed, then a minute or so later, ramped up to final speed.
    5) Stopped turbomolecular pump.  Allowed several minutes for pump to coast down.
    6) Bled pressure to atmospheric. Removed regular vacuum pump.
