Marwell’s MST-100 is a meter socket tester that is designed to test electric meter sockets for proper wiring prior to setting a kWH meter. Improperly wired meter sockets can be potentially dangerous to the meter installer. In addition to detecting short circuits, improper grounding and reverse-feed wiring errors associated with the meter socket, the MST-100 includes an analog meter that displays any current that may be flowing into the load. By following a few simple steps, the meter installer can use the MST-100 as a tool to verify proper wiring of a meter socket.
