Feature <br />Slide wire rheostatUseful as a basic component for any electrical laboratory <br />Madeof oxidized resistance wire of copper nickel alloy <br />Metal end supports with provision for screw mounting <br /> <br />Usage <br />1.Whenadjustingthe current in the circuit,slide rheostat should keepSeries Connectioninthe circuit, and keep theresistanceof the Rheostat up to maximum. Then connecting the power supply,slide the conductive brush,gradually reducing resistance to make the current suitable. <br />2.When adjusting the voltage of the circuit between two points,slide rheostat shouldParallelConnection in circuit,and keep theresistanceof the Rheostat down tominimum.Then connecting the power supply,slide the conductive brush,gradually reducing resistance to makevoltage ofthe currentendssuitable. <br /> <br />Note <br />1.When using the rheostat, it should not be too close to the heat source. <br />2.Rheostat long-term use may cause poor contact between oxidation insulation and the resistance wire brush. Before using, it should be wiped away the oxide layer. Long vibration and other reasons,it may appear screw loose,sliderloose and other illnesses , pay attention to check eliminated. <br />3.Rheostat should not exceed the rated maximum load. <br /> <br /> <br /> <br /> <br /> <p style="font-size: 11px; color: #919191; "><u><b>For CALIFORNIA residents only: </b></u></p> <p style="font-size: 11px; color: #919191; ">WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.<br /><b>Please note that by posting this Proposition 65 warning, we are notifying you that one or more of the Proposition 65 listed chemicals may be present in a product.
