Keysight Technologies E5400-Pro Series Soft Touch Connectorless Probes User's Guide
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."
• 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 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.
• 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 gases 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.
