| 摘要 |
<p>The present invention, in one embodiment, is a method for measuring electricity usage that includes steps of: coupling a sensor (104, 106) to a power source (102); converting a signal from the sensor to a digital measurement signal (112); using a microcomputer (114) to determine quantities indicative of electricity consumption from the digital measurement signal (112); and using a nonvolatile, reprogrammable memory (120) coupled to the microcomputer (114) to control the microcomputer (114) in determining the quantities indicative of electricity consumption.</p> |
