SAFETY
AND
EQUIPMENT
PROTECTION
PRECAUTIONS
1.
Check your line voltage
before
use. The oscilloscope voltage rating
appears
on the back of the set. If your line voltage is different from the oscilloscope's
rating,
there
is a
danger
of malfunctioning. You should plug in the cord only
after making sure
that
the two voltage ratings are the same.
2.
The oscilloscope is equipped
with
internal
components
that
are highly charged
electrically.
For your own protection, do not for any reason remove the
set's
casing.
3.
Use this oscilloscope indoors.
This
oscilloscope is designed for indoor use only. Do not use it
outdoors.
If
it
is used
outdoors,
water
penetrates
into the oscilloscope through the vent
holes when it rains or snows, causing short
circuit,
electric shocks, electro-
cution or
other dangerous
accidents.
4.
Do not
lock
the vent holes.
Do
not place this oscillocope close to the
wall,
other
instruments or the
like.
Do
not place any object on this oscilloscope. If the vent holes of the casing
are blocked, the
temperature
inside the oscilloscope rises excessively,
resulting in the possibility of smoke,
fire
or
other
accidents.
5.
Do not use the oscilloscope in the following locations.
# In direct sunlight.
# In extremely hot
and/or
humid areas.
®
In areas affected by high levels of mechanical vibration.
# Around areas
with
strong lines of magnetic force or impulse voltage.
# A place where explosive gas or vapor is produced or stored.
6. Make sure
that
the voltage applied to each input terminal
does
not exceed the
maximum
amounts
specified.
A
CHI,
CH2 and
EXT.TRIG
input terminals: 800Vp-p or
400V(DC+ACpeak)
A
Z.AXIS
input terminals: 84Vp-p or 42
V(DC+ACpeak)
Moreover, do not
under
any circumstances apply voltage to the
output
termi-
nals from external power sources.
