Introduction

Introduction

Chapter 3 describes how to use the instrument features that were introduced in Chapter

2.The introductory information in Chapter 2 is designed to give you a feel for the instrument’s controls and display. The information presented here in Chapter 3 adds more detail about connecting and operating the instrument.

Operating Modes

The instrument has three modes of operation. These modes are summarized as follows:

∙Active Mode

The instrument is in Active Mode whenever the Monitor and/or Scan functions are enabled; "MON" and/or "SCAN" annunciators are lighted, as appropriate. Note that the Scan function can be activated by the scan interval timer, external trigger, alarm trigger, or a single scan command.

∙Configuration Mode

The instrument is in Configuration Mode whenever any of the settings are being examined or changed. Examples of Configuration Mode are: channel function selection, alarm value setting, Mx+B scaling value setting, scan interval setting, and trigger type selection. During Configuration Mode, the "SET" annunciator is on, along with other annunciators indicating the parameter being set. Configuration Mode is summarized in Figure 3-1.

∙Inactive Mode

The instrument is in Inactive Mode when no measurement functions are enabled and no instrument settings are being changed. This is a quiescent mode, from which Active or Configuration Mode can be entered. The display presents summary information, identifying the channel number (brightly lit, right display) and its present function (dimly lit annunciator).
