Safety
Notices
This apparatus has been designed and tested in accor- dance with IEC Publication 1010, Safety Requirements for Mea- suring Apparatus, and has been supplied in a safe condition. This is a Safety Class I instru- ment (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 instru- ment 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 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
•Only fuses with the required rated current, voltage, and spec- ified 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 isola- tion), the common terminal must be connected to the earth termi- nal 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 per- son, 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 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 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 clean- ing: (1) Remove power from the instrument. (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.
