Safety Notices
7000 Series Oscilloscopes Service Guide
This apparatus has been designed and tested in accordance
with IEC Publication 1010, 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."
Warnings
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 conduc-
tor (grounding). Grounding one conductor of a two-conductor outlet is not sufficient protec-
tion.
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 or fire hazard.
If you energize this instrument by an auto transformer (for voltage reduction or mains isola-
tion), the common terminal must be 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.
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 adjust-
ment unless another person, capable of rendering first aid and resuscitation, is present.
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.
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 use the instrument in a manner not specified by the manufacturer.
To clean the instrument
If the instrument requires cleaning: (1) Remove power from the instrument. (2) Clean the
external surfaces of the instrument with a soft cloth dampened with a mixture of mild deter-
gent and water. (3) Make sure that the instrument is completely dry before reconnecting it to
a power source.
