with regard to this
material, including, but

Safety
This apparatus has been
designed and tested in
accordance with IEC
Publication 348, Safety
Requirements for Measuring
Apparatus, and has been
supplied in a safe condition.
This is a Safety Class I
instrument (provided with
terminal for protective
earthing). Before applying
power, verify that the correct
safety precautions are taken
(see the following warnings).
In addition, note the external
markings on the instrument
that are described under
"Safety Symbols."
Warning
•
Before turning on the
instrument, you must connect
the protective earth terminal
of the instrument to the
protective conductor of the
(mains) power cord. The
mains plug shall only be
inserted in a socket outlet
provided with a protective
earth contact. You must not
negate the protective action
by using an extension cord
(power cable) without a
protective conductor
(grounding). Grounding one
conductor of a two-conductor
outlet is not sufficient
protection.
•
Only fuses with the
required rated current,
voltage, and specified type
(normal blow, time delay,
etc.) should be used. Do not
use repaired fuses or
short-circuited fuseholders.
To do so could cause a shock
of fire hazard.
•
Service instructions are for
trained service personnel. To
avoid dangerous electric
shock, do not perform any
service unless qualified to do
so. Do not attempt internal
service or adjustment unless
another person, capable of
rendering first aid and
resuscitation, is present.
•
If you energize this
instrument by an auto
transformer (for voltage
reduction), make sure the
common terminal is
connected to the earth
terminal of the power source.
•
Whenever it is likely that
the ground protection is
impaired, you must make the
instrument inoperative and
secure it against any
unintended operation.
•
Do not operate the
instrument in the presence of
flammable gasses or fumes.
Operation of any electrical
instrument in such an
environment constitutes a
definite safety hazard.
•
Do not install substitute
parts or perform any
unauthorized modification to
the instrument.
•
Capacitors inside the
instrument may retain a
charge even if the instrument
is disconnected from its
source of supply.
•
Use caution when exposing
or handling the CRT.
Handling or replacing the
CRT shall be done only by
qualified maintenance
personnel.
