This apparatus has been designed and tested in accordance with IEC Publication
EN 61010-1:2001, 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 be inserted only 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 fuse holders. 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.
