Internal Fuses
In addition to the line fuse that can be replaced by
the operator (see “Replacing the Fuse”), there are
fuses mounted on printed circuit assemblies inside
the Calibrator. These fuses cannot be replaced by
the operator. For fuse locations and descriptions,
refer to “Internal Fuse Replacement” in Chapter 7
of the
5520A Operators Manual
. For instructions
on replacing an internal fuse, refer to the
