Additional 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 reconnect-
ing it to a power source.
