It is designed for measurement of the resistance of earthen used in the electrical equipment as well as for measurement of ground resistivity. It can be used for measurements of the other low regular and liquid resistances. It can also be used for measurement of voltage AC, voltage DC and earth voltage. This instrument finds wide application for testing earthen installation in power based industries, telecommunication networks and electrical traction systems etc
