Power for panel meter:
Most meter modules using a liquid-crystal display (LCD) and some using a light-emittingdiode (LED) display need a power source that is isolated from the measurand. In practice, this normally means that a separate battery has to be used. This is cumbersome and can be avoided with the circuit described in this article.
