Safety Notices
This apparatus has been
designed and tested in accor-
dance with IEC Publication
EN 61010-1:2001, Safety Require-
ments for Measuring Apparatus,
and has been supplied in a safe
condition. This is a Safety Class I
instrument (provided with termi-
nal for protective earthing).
Before applying power, verify that
the correct safety precautions are
taken (see the following warn-
ings). In addition, note the exter-
nal markings on the instrument
that are described under "Safety
Symbols."
Warnings
• Before turning on the instru-
ment, you must connect the pro-
tective earth terminal of the
instrument to the protective con-
ductor of the (mains) power cord.
The mains plug shall only be
inserted in a socket outlet pro-
vided with a protective earth con-
tact. You must not negate the
protective action by using an
extension cord (power cable)
without a protective conductor
(grounding). Grounding one con-
ductor of a two-conductor outlet
is not sufficient protection.
• Only fuses with the required
rated current, voltage, and speci-
fied 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 haz-
ard.
• If you energize this instrument
by an auto transformer (for volt-
age 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 inoper-
ative 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 adjustment
unless another person, capable of
rendering first aid and resuscita-
tion, is present.
• Do not install substitute parts or
perform any unauthorized modifi-
cation to the instrument.
• Capacitors inside the instru-
ment 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 gas-
ses or fumes. Operation of any
electrical instrument in such an
environment constitutes a defi-
nite safety hazard.
• Do not use the instrument in a
manner not specified by the man-
ufacturer.
To clean the instrument
If the instrument requires clean-
ing: (1) Remove power from the
instrument. (2) Clean the external
surfaces of the instrument with a
soft cloth dampened with a mix-
ture of mild detergent and water.
(3) Make sure that the instru-
ment is completely dry before
reconnecting it to a power
source.
