Accessing the Fuse
To prevent instrument damage, verify that
the correct fuse is installed for the line
voltage setting. Acceptable fuse types are
Bussman type MTH or Littelfuse type 312 or
equivalent, of the appropriate amperage
rating. Use only a 4A, 250V fast-blow fuse
when the line voltage selection switches are
set in the range 200-240V.
A spare 4A, 250V fuse is shipped with the 5725A
to ensure that one is available for use on the
200-240V range.

Note
The line power fuse is accessible on the rear panel. The
fuse rating label to the right of the fuse holder (labeled

refer to Figure 5 and proceed as follows:
1.
Turn off the POWER switch and disconnect the line
power cord from ac line power.
2.
Insert the blade of a standard screwdriver in the slot
of the fuse holder labeled FUSE.
3.
Turn the screwdriver counterclockwise until the cap
and fuse pop free.
4.
To reinstall the fuse, reverse this procedure.
