It is mainly used by the power transmission and distribution company of a country. The cost of meter testing bench is very high and a few companies fabricate this machine. In this paper a simple and a low cost design of a meter testing bench is illustrated. The hardware and software components used in the design are cheap and widely available in the markets.
