Part Replacement
Fuse
Refer to the instructions when replacing the fuses. The table contains part numbers for the replacement fuse and fuse drawer.
To change a fuse, follow these steps.
1 Power off the instrument and disconnect the power cord.
2 Locate or order replacement fuses. (Extras were provided with the
instrument.)
3 Place a small screwdriver or a fingernail under the tab on the fuse drawer
to detach it.
4 Remove the fuse drawer from its receptacle on the rear panel.
5 Replace both fuses. Use only fuses with the rated current and specified
type as listed in this user’s guide and on the rear panel of the instrument.
6 Insert the fuse drawer into its receptacle on the rear panel.
A blown fuse may indicate the existence of another problem in the instrument. If the replacement fuses blow, do not try others.
