Introduction 1

Where to go from Here

Chapter 2: Getting started

Explains how to prepare the meter for operation and get started quickly taking basic measurements from the front panel.

Chapter 3: Operating the meter from the front panel

Provides a complete description of each operation that can be performed using the push- buttons on the front panel. Chapter 3 is organized so that related operations and functions are grouped together.

Chapter 4: Applications

Describes how to use the meter in more advanced operations and sophisticated applica- tions. Assumes a basic knowledge of the meter and front panel operations.

Chapter 5: Operating the Meter using the Computer Interface

Describes how to connect the meter to a terminal or host and operate it via the RS-232-C or (optional) IEEE-488 interface. Assumes a basic knowledge of the meter and front panel operations.

Chapter 6: Maintenance

Describes how to perform basic maintenance and repairs (e.g., replacing fuses) and how to order replacement parts. Complete service and repair procedures are contained in the "Fluke 45 Dual Display Multimeter Service Manual" (P/N 856042).
