Power Requirements
The Model 4314B can operate from two different power sources. The wattmeter
comes supplied with two 9 V alkaline batteries which typically provide 20 hours
of operation. An AC wall supply is also available for use with either a 115 or 230
VAC line.
Additional Equipment
The only additional equipment required by the Model 4314B is a Plug-In Ele-
ment (see table below). Most of them are designed to read both average and
peak power. Some are designed exclusively for peak reading application.
