General 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.
Warning No operator serviceable parts inside. Refer servicing to qualilled
personnel. To prevent electrical shock, do not remove covers.
Caution Before switching on this instrument, make sure that the line voltage selector
switch is set to the voltage of the power supply and the correct fuse is
installed.
Warning The opening of covers or removal of parts is likely to expose dangerous
voltages. Disconnect the instrument from all voltage sources while it is
being opened.
Warning The power cord is connected to internal capacitors that may remain live
for 10 seconds after disconnecting the plug from its power supply.
Warning For continued protection against fire hazard, replace line fuse only with
same type and rating (F 3A/250V). The use of other fuses or material is
prohibited.
Warning If this instrument is used in a manner not specilled by Hewlett-I%&a.rd
Co., the protection provided by the instrument may be impaired.
Note This instrument has been designed and tested in accordance with IEC
Publication 348, Safety Requirements for Electronics Measuring Apparatus, and
has been supplied in a safe condition. This 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.
