 The Intel ® Energy Checker API helps Software developers to easily instrument their software to expose metrics of " useful work " done by the software . For example , the amount of useful work done by a video serving application is number of frames processed , for a mail server application the useful amount of work done may be number of emails processed . The core Intel ® Energy Checker API consists of five basic functions . These functions include Open , Re - open , Read , Write , and Close . The SDK comes with utilities to measure the energy consumed by the software on Intel server platforms using power analyzers . Power analyzers supported in this SDK include Yokogawa ' s WT 210 , WT 230 , WT 500 , WT 300 , WT 3000 , WT 300 E , & WT 3000 E . To learn more about Yokogawa Power Analyzers , please click here .

 A power analyzer measures electrical power characteristics of devices that generate , transform , or consume electricity . Also called power meters or wattmeters , these devices measure parameters such as true power ( watts ) , power factor , harmonics and efficiency in inverters , motor drives , lighting , home appliances , office equipment , power supplies , industrial machinery and other devices . Power analyzers also enable engineers to minimize energy loss due to distorted , transient waveforms in power electronics such as inverters , motors , lighting circuits , and power supplies . Yokogawa , the world ' s leading manufacturer of electrical power analyzers , provides a broad selection to satisfy all requirements . Digital Power Analyzers
