Setting line voltage and replacing fuse
A rear panel fuse located next to the AC receptacle protects the power line input of the instru-
ment. If the line voltage setting needs to be changed or the line fuse needs to be replaced, per-
form the following steps.
WARNING
Make sure the instrument is disconnected from the AC line and other equip-
ment before changing the line voltage setting or replacing the line fuse.

Place the tip of a 鏗俛t-blade screwdriver into the power module by the fuse holder assem-
bly (see Figure 2-3). Gently push in and to the left. Release pressure on the assembly and
its internal spring will push it out of the power module.
Remove the fuse and replace it with the type listed in Table 2-1.
For continued protection against 鏗乺e or instrument damage, only replace
fuse with the type and rating listed. If the instrument repeatedly blows fuses,
locate and correct the cause of the trouble before replacing the fuse. See the
