Introduction
This section describes routine type maintenance that can be performed by the operator and
includes procedures for replacing both the line fuse and the amps fuse.
Setting the line voltage and replacing the line fuse
WARNING Disconnect the line cord at the rear panel, and remove all test leads
connected to the instrument (front and rear) before replacing the line fuse.
The power line fuse is located in the power module next to the AC power receptacle (see
Figure 3-1). If the line voltage must be changed or if the line fuse requires replacement, perform
the following steps:
1. Place the tip of a flat-blade screwdriver into the power module by the fuse holder
assembly (see Figure 3-1). Gently push in and turn to the left. Release pressure on the
assembly, and its internal spring will push it out of the power module.
