1-4. Organization of the Service Manual
This manual focuses on component-level repair of the Fluke 45 Dual Display
Multimeter. To that end, manual chapters are often interdependent; effective
troubleshooting may require not only reference to the troubleshooting procedures in
Chapter 5, but also some understanding of the detailed Theory of Operation in Chapter 2
and some tracing of circuit operation in the Schematic Diagrams presented in Chapter 9.
Often, scanning the table of contents will yield an appropriate place to start using the
manual. A comprehensive table of contents is presented at the front of the manual; local
tables of contents are also presented at the beginning of each chapter for ease of
reference. If you know the topic name, the index at the end of the manual is probably a
good place to start.
The following chapter descriptions serve to introduce the manual:
Chapter 1. Introduction and Specifications

accessories. This chapter also discusses use of the Service Manual and the various
