Figure 40: Fuse replacement
Line fuse is in a similar location on the other 2600B models.
To prevent injury, death, or instrument damage, use only the correct fuse type (see the Line
Fuse table below).
To replace the line fuse:
1. Power off the instrument and remove the line cord.
2. The fuse drawer (item 1 in the previous figure) is below the ac receptacle. A small tab is on the
top of the fuse drawer (item 2). Use a thin-bladed knife or a screwdriver to pry this tab away from
the ac receptacle.
3. Slide the fuse drawer out to gain access to the fuse (the fuse drawer does not pull completely out
of the power module).
4. Snap the fuse out of the drawer and replace it with the same type (the fuse is specified in the
following table).
5. Push the fuse drawer back into the module.
If a fuse continues to become damaged, a circuit malfunction exists and must be corrected. Return
the instrument to Keithley Instruments for repair.
