3.2.1 Line power connections

Follow the procedure below to connect the Model 2001 to
line power and turn on the instrument.
1. The Model 2001 operates from a line voltage in the
range of 90-134V or 180-250V at a frequency of 50, 60,
or 400Hz. Check to see that the operating voltage in
your area is compatible.
2. Before plugging in the power cord, make sure the front
panel power switch is in the off (0) position.
