Portable Wheatstone Bridge

This bridge is fully portable with a built in sensitive Galvanometer and a dry battery. The bridge is extremely useful for resistance measurements with a fair degree of precision. Series Arm : • There are 4 decades of 10 x 1, 10 x 10, 10 x 100 and 10 x 1000 ohms. Range Multiplier : • A single rotary switch furnishes 7 range multipliers of x 1000, x100, x10, x1, x0.1, 0.01 and 0.001. Range of Measurement : • Ohm to 1.11 mega ohms. Battery : • A dry battery of 4.5 volts is built-in provision is there for using external battery for measuring high resistances.
