Functions and Operations

Introduction

This chapter provides a brief overview of the Site Master functions and operations, provid- ing the user with a starting point for making basic measurements. For more detailed infor- mation, refer to Chapter 4, Measurements and Chapter 5, Software Tools.

The Site Master is designed specifically for field environments and applications requiring

mobility. As such, it is a lightweight, handheld, battery operated unit which can be easily 2 carried to any location, and is capable of up to 2.5 hours of continuous operation from a

fully charged battery. Built-in energy conservation features allow battery life to be extended over an eight-hour workday. The Site Master can also be powered by a 12.5 VDC external source. The external source can be either the Anritsu AC-DC Adapter (P/N 40-115) or 12.5 Vdc Automotive Cigarette Lighter Adapter (P/N 806-62). Both items are standard accesso- ries.

Test Connector Panel

The connectors and indicators located on the test panel are listed and described below.

12.5-15VDC12.5 to 15 Vdc @ 1100 mA input to power the unit or for battery charging.

WARNING

When using the AC-DC Adapter, always use a three-wire power cable connected to a three-wire power line outlet. If power is supplied without grounding the equip- ment in this manner, there is a risk of receiving a severe or fatal electric shock.
