Power
The TriStar II Plus is designed to operate with a universal input power supply (100 / 115 / 230 VAC) at
50 or 60 Hz. Noise-free power of the correct voltage and frequency, with a safety earth ground, should
be available through a standard wall receptacle. The power outlet should be able to supply 15 amps @
100 or 115 VAC + 10% or 7.5 amps @ 230 VAC +10%. These requirements can be checked by using
a Circuit Analyzer (available at most hardware or electronic supply houses) or a multimeter. There
should also be sufficient outlets for the computer, dry roughing pump, monitor, and printer and any
other peripheral devices.
DO:
• Install the instrument and peripheral devices on their own, dedicated power line.
DO NOT:
• Place other devices on the same power line; for example, motors, generators, or ovens.
