PREPARATION FOR USE
SAFETY
Before
connecting
the
instrument
to a power
source,
carefully read the following information,
then verify that
the proper power cord is used and the proper line fuse is in-
stalled for power source. The specified voltage is shown at
the left side of the power cord on the rear panel. If the
power
cord is not applied for specified voltage, there is
always a certain amount of danger from electric shock.
Line voltage
This
instrument
operates
using ac-power
input voltages
that
100/120/220/240 V at frequencies
from
50 Hz to
60 Hz.
Power cord
The ground wire of the 3-wire ac power plug places the
chassis and housing of the oscilloscope at earth ground. Do
not attempt to defeat the ground wire connection or float
the oscilloscope; to do so may pose a great safety hazard.
The appropriate power cord is supplied by an option that is
specified when the instrument is ordered.
The optional power cords are shown as follows in Fig. 1.
Line fuse
The fuse holder is located on the rear panel and contains
the line fuse. Verify that the proper fuse is installed by
replacing the line fuse.
EQUIPMENT PROTECTION
1. Never allow a small spot of high brilliance to remain sta-
tionary on the screen for more than a few seconds. The
screen may become permanently burned. A spot will oc-
cur only when the scope is set up for X-Y operation and
no signal is applied. Either reduce the intensity so the
spot
is barely visible,
switch
back to normal
sweep
operation when no signal is applied, or set up the scope
for spot blanking.
2. Never
cover
the ventilating
holes on the top of the
oscilloscope,
as
this
will
increase
the
operating
temperature inside the case.
3. Never
apply
more
than
the
maximum
rating to the
oscilloscope inputs.

4. Always connect a cable from the earth grouind (GND)
jack of the oscilloscope to the chassis of the equipment
under test. Without this caution, the entire current for
the equipment
under test may
be drawn through the
probe clip leads under certain circumstances,
