Safety
Notices
This apparatus has been
designed and tested in accor
-
dance 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 warn
-
ings). In addition, note the
external markings on the
instrument that are described
under "Safety Symbols."
Warnings
• Before turning on the instru-
ment, you must connect the
protective earth terminal of
the instrument to the protec
-
tive 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 protec
-
tive action by using an exten-
sion cord (power cable)
without a protective conduc
-
tor (grounding). Grounding
one conductor of a two-con-
ductor 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 fuse
-
holders. To do so could
cause a shock or fire hazard.
• If you energize this instru-
ment by an auto transformer
(for voltage reduction or
mains isolation), 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 unin
-
tended 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 adjustment unless
another person, capable of
rendering first aid and resus
-
citation, is present.
• Do not install substitute
parts or perform any unautho
-
rized modification to the
instrument.
• Capacitors inside the instru-
ment may retain a charge
even if the instrument is dis
-
connected from its source of
supply.
• Do not operate the instru-
ment in the presence of flam-
mable gasses or fumes.
Operation of any electrical
instrument in such an envi
-
ronment constitutes a defi-
nite 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 detergent and water. (3)
Make sure that the instru
-
ment is completely dry before
reconnecting it to a power
source.
