Chapter 2. Theory of Operation
This chapter first categorizes meter circuitry into functional blocks, with a description of
each block’s role in overall operation. A detailed circuit description is then given for
each block. These descriptions explore operation to the component level and fully
support troubleshooting procedures defined in Chapter 5.
Chapter 3. General Maintenance
Provides maintenance information covering handling, cleaning, and fuse replacement.
Access and reassembly procedures are also explained in this chapter.
Chapter 4. Performance Testing and Calibration
This chapter provides performance verification procedures that are tied to the
specifications presented in Chapter 1. To maintain these specifications, a full calibration
procedure is also presented.
Chapter 5. Diagnostic Testing and Troubleshooting
The troubleshooting procedures presented in this chapter rely closely on both the Theory
of Operation presented in Chapter 2 and the Schematic Diagrams shown in Chapter 9.
Chapter 3 provides access information.
Chapter 6. List of Replaceable Parts
Includes parts lists for all standard assemblies. Information on how and where to order
parts is also provided.
Chapter 7. Option -01 Battery Pack
Each option is allocated a separate chapter: 7 for the Battery Pack Option -01 and 8 for
the IEEE-488 Interface Option -05. Option -15 incorporates both Options -01 and -05.
Chapter 7 includes the full range of Service Manual topics (specifications, theory of
operation, maintenance, list of replaceable parts, etc.) for the Battery Pack option.
Schematic diagrams for the options are found in Chapter 9.
Chapter 8. Option -05 IEEE-488 Interface
Includes the full range of Service Manual topics (specifications, theory of operation,
maintenance, list of replaceable parts, etc.) for the IEEE-488 Interface option. Schematic
diagrams for the options are found in Chapter 9.
Chapter 9. Schematic Diagrams
Includes schematic diagrams for all standard and optional assemblies. A list of
mnemonic definitions is also included to aid in identifying signal name abbreviations.
1-5. Conventions
Throughout the manual set, certain notational conventions are used. A summary of these
conventions follows:
• Instrument Reference
The Fluke 45 Dual Display Multimeter is usually called the "meter."
• Printed Circuit Assembly
