HP 4934A User Manual

WA R NIN G 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 only (in which aU means for protection are intact).
Preparation for Use
WA R NIN G To avoid the possibility of injury or death, the following precautions must be
followed before the instrument is switched on.
A. Note that the protection provided by grounding the instrument cabinet may
be lost if any power cable other than the three-pronged type supplied is used to
couple the AC line voltage to the instrument.
B. If this instrument is to be energized via an auto-transformer to reduce or
increase the line voltage, make sure that the common terminal is connected to
the neutral pole of the power source.
C. The power cable plug shall only be inserted into a socket outlet provided with
a protective earth contact. The protective action must not be negated by the use
of an extension cord without a protective conductor (grounding).
Power Requirements
The instrument requires a power source of 90 to 126 V AC, 48 to 66 Hz
single phase. If necessary, the 4934A can be changed to 198-264 V AC, 48
to 66 Hz using an internal switch. Check instructions before doing so and
ensure the correct fuse is used. The power consumption is less than 20 VA.
Line Fuse
The line fuse is located on the side panel.
WA R NIN G For continued protection against fire hazard, replace the line fuse only with the
same type and line rating (F 125mA, 250V for 230V operation or F 250mA, 2S0V
for 15V operation). The use of other fuses or materials is prohibited.
