Abstract
A panel meter including an energy test pulse device that enables the panel meter to be used for revenue applications and eliminates the need for two separate meters, one for panel indication, and the other for energy and revenue applications. The electrical panel meter including at least one sensor configured for measuring an electrical parameter; at least one analog-to-digital converter coupled to the at least one sensor for converting the measured electrical parameter to a digital signal; a display for continuously displaying at least one electrical parameter; a processor configured to receive the digital signal and calculate an amount of energy consumed; and a test pulse circuit configured to receive the calculated amount and generate a plurality of pulses equal to the calculated amount, wherein each of the plurality of pulses is equal to a predetermined amount of energy.
