Fuse replacement
A rear panel fuse drawer is located below the AC receptacle (refer to Figure 1-2 for Models 2601A/
2602A/2611A/2612A and Figure 1-3 for Models 2635A/2636A). This fuse protects the power line
input of the instrument. If the line voltage fuse needs to be replaced, refer to Line fuse replacement
in Section 21.
