Introduction
This section provides maintenance information and procedures that can be performed by the
operator.
Line fuse replacement
A fuse located on the Model 2110 rear panel protects the power line input of the instrument.
Disconnect the line cord at the rear panel and remove all test leads connected to the
instrument before replacing the line fuse. Failure to do so could expose the operator to
hazardous voltages that could result in personal injury or death.
The power line fuse is accessible from the rear panel, adjacent to the AC power receptacle, as shown
in the following figure.
