Chapter 1 Introduction

1.1 About This Manual

This manual is intended for the user of the

PM130

Powermeter.

The

PM130

is a microprocessor-based instrument used for meas-

urement, monitoring, and management of electrical parameters.

This chapter gives an overview of this manual and an introduction
to the

PM130

Chapter 2,

Installation

, provides instructions for mechanical and

electrical installation.

Chapter 3,

Using the Menus

, presents the structure of menus for

setup and status viewing.

Chapter 4,

Setup Menus

, provides instructions for performing

parameter setup via the front panel.

Chapter 5,

Data Display

, guides you through the display pages.

Chapter 6,

Viewing Status Information

, tells you how to access

additional status information on the instrument. This information
may be useful during installation.

Technical Specifications

for the

PM130

are found in the Appendix.

1.2 About The

PM130

The

PM130

a compact panel mounted 3-phase AC Powermeter,

specially designed to meet the requirements of users ranging from
electrical panel builders to substation operators. The

PM130

available in three models: the

PM130

for basic voltage, current

and frequency measurements; the

PM130P

which adds power and

power factor measurements; and the

PM130E

which adds power

demands and energy measurements. All models are suitable for
mounting on both 4-inch round and 92x92mm square cut-outs.

Features

Display:

The front panel features bright LED displays (three

windows, up to 38 pages) with adjustable display update time, and
a LED

bar graph

showing percentage load with respect to user-

definable nominal (100%) load current. In the common
measurements group (see Chapter 5),

Display Auto Scroll

available with a programmable scroll interval of 2 to 15 seconds.
