mation, refer to Chapter 4, Measurements and Chapter 7, 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
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
