The wattmeter can accurately measure highly distorted power signals in a frequency range from 1 Hz to 100 kHz. Asynchronous sampling techniques are used by the wattmeter, and the errors associated with this type of operation are described in detail. Methods of correcting some of these errors are also described. A new feature of this sampling wattmeter is the use of programmable time delay circuits to compensate for differential time delays between the two input channels. This is necessary for accurate measurements at higher frequencies. Performance tests of the wattmeter, which show that it has a measurement uncertainty of less than 1% over a wide frequency range, are presented. The detailed circuit diagrams of this wattmeter are provided to allow for replication. The book also includes software programs written in Pascal. This book will be of interest to electrical engineers and others who work with power measurement. It is a valuable resource for anyone who wants to learn about the design and operation of sampling wattmeters.
