Equipment Operation
Warnings and Cautions
This guide uses warnings and cautions to denote hazards.
WARNING A warning calls attention to a procedure, practice or the
like, which, if not correctly performed or adhered to, could
result in injury or the loss of life. Do not proceed beyond a
warning until the indicated conditions are fully
understood and met.
Caution A caution calls attention to a procedure, practice or the like which,
if not correctly performed or adhered to, could result in damage to
or the destruction of part or all of the equipment. Do not proceed
beyond a caution until the indicated conditions are fully
understood and met.
Personal Safety Considerations
WARNING This is a Safety Class I product (provided with a protective
earthing ground incorporated in the power cord). The
mains plug shall only be inserted in a socket outlet
provided with a protective earth contact. Any interruption
of the protective conductor, inside or outside the
instrument, is likely to make the instrument dangerous.
Intentional interruption is prohibited.
If this instrument is not used as specified, the protection
provided by the equipment could be impaired. This
instrument must be used in a normal condition (in which
all means of protection are intact) only.
No operator serviceable parts inside. Refer servicing to
qualified personnel. To prevent electrical shock, do not
remove covers.
For continued protection against fire hazard, replace the
line fuse(s) only with fuses of the same type and rating (for
example, normal blow, time delay, etc.). The use of other
fuses or material is prohibited.

General Safety Considerations
vi HP E4418B/E4419B Programming Guide
General Safety Considerations
WARNING Before this instrument is switched on, make sure it has
been properly grounded through the protective conductor
of the ac power cable to a socket outlet provided with
protective earth contact.
Any interruption of the protective (grounding) conductor,
inside or outside the instrument, or disconnection of the
protective earth terminal can result in personal injury.
Caution Any adjustments or service procedures that require operation of
the instrument with protective covers removed should be
performed only by trained service personnel.
Markings
The CE mark shows that the product complies with
all the relevant European legal Directives (if
accompanied by a year, it signifies when the design
was proven.
This is the symbol of an Industrial Scientific and
Medical Group 1 Class A product.
The CSA mark is a registered trademark of the
Canadian Standards Association.
External Protective Earth Terminal.
While this is a Class I product, provided with a
protective earthing conductor in a power cord, an
external protective earthing terminal has also been
provided. This terminal is for use where the earthing
cannot be assured. At least an 18AWG earthing
conductor should be used in such an instance, to
ground the instrument to an assured earth terminal.

IEC 1010-1 Compliance
This instrument has been designed and tested in accordance with IEC
Publication 1010-1 +A1:1992 Safety Requirements for Electrical
Equipment for Measurement, Control and Laboratory Use and has been
supplied in a safe condition. The instruction documentation contains
information and warnings which must be followed by the user to ensure
safe operation and to maintain the instrument in a safe condition.
Statement of Compliance
This product has been designed and tested for compliance with IEC 60529
(1989) Degrees of Protection Provided by Enclosures (IP Code). Level IPx4
is attained if, and only if, the carry case( part number HP 34141A) is
fitted.
User Environment
This product is designed for use in a sheltered environment (avoiding
extreme weather conditions) in accordance with Pollution Degree 3
defined in IEC 60664-1, with the carry case ( part number HP 34141A)
fitted over the instrument.
The product is suitable for indoor use only, when this carry case is not
fitted.
Installation Instructions
To avoid unnecessary over-temperature conditions, while this carry case is
fitted do not apply an ac mains supply voltage, only operate your power
meter from the battery pack.
