Product Safety Notices
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 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 or fire hazard.
If you energize this instrument 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 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
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
detergent and water. (3) Make
sure that the instrument is
completely dry before
reconnecting it to a power source.
