5725A

Instruction Manual

2-8. Accessing the Fuse

Caution

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.

Note

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.
