Our spot reflecting galvanometer of low resistance is recommended to be connected to terminals marked “GALVO” on the bridge. It operates on 220 volts A.C. mains. The coil is set free by turning the pointed knob in the “FREE” position. The spot of light is set   in the center of scale by using the zero adjuster. While finding null point with the galvanometer, use initially higher shunt power of 1/1000, 1/10. As null point approaches, the position “1” should be used. At this position of shunt, the galvanometer sensitivity maximum.
