ABOUT THIS MANUAL

Chapter 1 Introducing the ScopeMeterTest Tool

This chapter introduces features and capabilities of your

ScopeMeter test tool.

Chapter 2 Getting Started

This chapter provides a 15-minute demonstration intended

for those who are not familiar with the ScopeMeter test

tool.

Chapter 3 Making Measurements

This chapter explores all measurements and specifies the

use of the direct Measure Menu key. At any time, you can

choose over 30 measurements to get an immediate

reading on the display.

Chapter 4 Using the Dual Display Mode

This chapter addresses the use of four Dual Display Mode

Functions of the ScopeMeter test tool: , , , and

. You will learn how to set up the test tool for ac and

dc voltage measurements, diode tests, resistance

measurements, and trend plotting. Chapter 5 contains all

the Scope mode information.

Chapter 5 Using the Scope Mode

This chapter explores the specific use of the test tool as a

digital storage oscilloscope. You will learn how to make,

store, and compare measurements.

Chapter 6 Using Additional Capabilities

This chapter explores the additional capabilities available

with your ScopeMeter test tool. The chapter covers

subjects, such as Scope measurements using the cursors,

saving and recalling screens, waveforms, or setups, and

making a hard copy on your printer.

Chapter 7 Measuring Examples

This chapter outlines step-by-step procedures necessary

to make some typical measurements.

Chapter 8 ScopeMeter Test Tool Tutorial

This chapter looks at special capabilities of your

ScopeMeter test tool. You will become familiar with all

aspects by using the demonstration board.

Chapter 9 User Maintenance

This chapter describes the cleaning of the ScopeMeter test

tool and proper use and replacement of the battery pack.

Periodic probe calibration is also covered here.

WARNING

READ "SAFETY" CAREFULLY BEFORE USING YOUR

SCOPEMETER TEST TOOL.

SAFETY

The instrument described in this manual is designed to be

used only by qualified personnel.

Safety Precautions

To use this instrument safely, it is essential that operating

and servicing personnel follow both generally accepted

safety procedures and the safety precautions specified in

this manual.

Specific warning and caution statements, where they

apply, will be found throughout the manual.

Where necessary, the warning and caution statements

and/or symbols are marked on the instrument.

A CAUTION identifies conditions and actions that may

damage the test tool.

A WARNING IDENTIFIES CONDITIONS AND ACTIONS

THAT POSE HAZARD(S) TO THE USER.

International electrical symbols used are explained below.

The terms "Isolated" or "Electrically floating" are used in

this manual to indicate a measurement in which the

ScopeMeter test tool COM (common, also called ground) is

connected to a voltage different from earth ground. The

term "Grounded" is used in this manual to indicate a

measurement in which the ScopeMeter test tool COM

(common) is connected to an earth ground potential.

The ScopeMeter test tool COM (common) inputs (red

INPUT A BNC shield, grey INPUT B BNC shield, and black

4-mm banana jack) are connected internally via self-

recovering fault protection. The input connectors have no

exposed metal and are fully insulated to protect against

electrical shock. The black 4-mm banana jack COM

(common) can be connected to a voltage above earth

ground for isolated (electrically floating) measurements

ments. The connections for isolated and grounded

measurements are shown in the following illustration.
