n the volt-meters the terminals are on opposite sides, are made small,and are usually covered with rubber, in order that theymay be handled without danger from shocks. Some of thevoltmeters are made with the resistance coils in two sec-tions, of such relative value that, when only one section isin… … on the left side, and the scale divisions have two values;for instance, the voltmeter with a range of 150 volts may-have the resistance so divided that by using the third bind-ing-post the range will be 15 volts and the scale divisionswill have yV their former value.
