Using a Digital Meter to Estimate Leaking Electricity

If your home has a fully solid-state digital kWh-meter, then you don't have a rotating disk to check. Instead, these meters have a "widget", that is, a light that moves across the display or flashes. The widget is supposed to represent the rotating disk and can be timed in a similar manner. Begin timing the instant the widget disappears from the display. Eventually the widget will reappear. Conclude the measurement when it disappears again. Calculate power consumption in the same way as for an electromechanical meter.
