Instruction Manual

2-8. 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.
The line power fuse is accessible on the rear panel. The fuse rating label to the right of
the fuse holder (labeled FUSE) shows the correct replacement fuse rating for each line
voltage setting. To check or replace the fuse, refer to Figure 2-4 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.
