POWER
UP
The following abbreviated information should be
enough to properly
and
safely power
up
the unit. How-
ever,
if
there are any uncertainties, refer to paragraph
2.2
for the complete power
up
procedure.
Line Voltage
The Source Measure Unit
is
designed to operate from
105-125Vor
210-235V
line power ranges. The operating
voltage that the instrument
is
configured to operate at
is
indicated on the line voltage slide switch located on the
rear panel (see Figure 1-15).
If
the alternate line voltage
setting
is
required, a
fuse
change will
be
required. The
procedure to configure the instrument to operate
at
the
alternate line voltage is located in paragraph 2.2.1.

Power Cord
Connect the female
end
of the power cord to the ac recep-
tacle on the rear panel of the instrument. Connect the
male
end
of the cord to a grounded ac outlet.
WARNING
The
Source
Measure
Unit
is
equipped
with
a
3-wire
power
cord
that
contains a separate
ground
wire
and
is
designed to
be
used
with
grounded
outlets. When
proper
connections
are made, instrument chassis
is
connected to
power
line ground. Failure to
use
a grounded
outlet
may
result
in
injury
or
death
due
to
electric shock.
CAUTION
Be sure
that
the
power
line
voltage agrees
with
the
indicated range
on
rear
panel
line
voltage switch. Failure to observe this
pre-
caution
may
result
in
instrument
damage
not
covered
by
the
warranty.
The
procedure to
configure
the
instrument for the alternate
line
voltage
is
found
in
paragraph 2.2.
Power Up
Cycle
To
turn
on
the instrument, press the
POWER button. The
Source Measure
Unit
will briefly display the installed
software revision
and
the
IEEE-488
bus address setting.
Complete details
on
the power
up
cycle, which includes
self tests, are contained in paragraph 2.2.4.
