Introduction

The information in this section deals with routine maintenance of the Keithley Instruments Model

2651A High Power System SourceMeter

A fuse located on the Model 2651A rear panel protects the power line input of the High Power System

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, just below the AC power receptacle (see the

following figure).
