Introduction
The information in this section describes routine maintenance of the instrument that the operator can
perform. It also contains information on how to optimize your measurements.
Line fuse replacement
Fuses on the 2606B rear panel protect 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 a line fuse. Failure to do so could expose the operator to
hazardous voltages that could result in personal injury or death.
The fuse drawer is above the AC receptacle on the rear panel of the 2606B, as shown in the following
figure.

To prevent injury, death, or instrument damage, use only the correct fuse type (see table).
