Safety
Notices
This apparatus has been
designed and tested in
accordance with IEC Pub-
lication 1010, Safety
Requirements for Measur-
ing Apparatus, and has
been supplied in a safe
condition. This is a Safety
Class I instrument (pro-
vided 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 mark-
ings on the instrument that
are described under
"Safety Symbols."
Warnings
• Before turning on the
instrument, you must con-
nect the protective earth
terminal of the instrument
to the protective conduc-
tor 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 exten-
sion cord (power cable)
without a protective con-
ductor (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 or
fire hazard.
• If you energize this
instrument by an auto
transformer (for voltage
reduction or mains isola-
tion), the common termi-
nal 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 inopera-
tive and secure it against
any unintended operation.
• Service instructions are
for trained service person-
nel. To avoid dangerous
electric shock, do not per-
form any service unless
qualified to do so. Do not
attempt internal service or
adjustment unless another
person, capable of render-
ing first aid and resuscita-
tion, 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 instru-
ment is disconnected from
its source of supply.
• Do not operate the
instrument in the pres-
ence of flammable gasses
or fumes. Operation of
any electrical instrument
in such an environment
constitutes a definite
safety hazard.
• Do not use the instru-
ment in a manner not
specified by the manufac-
turer.
To clean the instrument
If the instrument requires
cleaning: (1) Remove
power from the instru-
ment. (2) Clean the exter-
nal surfaces of the
instrument with a soft
cloth dampened with a
mixture of mild detergent
and water. (3) Make sure
that the instrument is
completely dry before
reconnecting it to a power
source. Safety Symbols
