3.2 Power-up procedure
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.
CAUTION
Operating the instrument on an incor-
rect line voltage may cause damage to
the instrument, possibly voiding the
warranty.
2. Before plugging in the power cord, make sure the front
panel power switch is in the off (0) position.
3. Connect the female end of the supplied power cord to
the AC receptacle on the rear panel. Connect the other
end of the power cord to a grounded AC outlet.
WARNING
The power cord supplied with the Model
2001 contains a separate ground wire
for use with grounded outlets. When
