Power Analyzer Packs Wealth Of Features

Promising high measurement accuracy and armed with numerous features, the Model WT3000 power analyzer provides a basic measurement accuracy of 0.02% with a bandwidth from dc to 1 MHz. It specifies a power-factor error of 0.03% of apparent power and a data update rate that can be set from 20 readings per second to one reading every 20 seconds. The instrument has a common mode voltage rating of 1 kV and features a unique simultaneous measurement mode of normal power parameters and harmonic analysis functions. As a result, users can measure the true RMS value of voltage and current without having to change the measurement mode. Other features include up to four inputs,input ranges from 7.5V to 1 kV and 0.25A to 30A, and 8.4" color LCD. A motor version of the analyzer is available for measuring outputs from a torque meter and speed transducer. YOKOGAWA CORP. OF AMERICA, Newnan, GA. (800) 258-2552.
