NV6030 Carey Foster’s Bridge Setup is used for the measurement of very low resistances, although it can be used to find small differences between large resistances. It can measure the decimal value of resistance. Our Carey Foster’s bridge Setup consists of two parts one is bridge arrangement and other one is its testing unit. Testing unit contains DC power supply, Galvanometer and adjustable resistances on a single board. DC power supply solves the problem of discharging a battery or a cell with respect to time which affects the result. Sensitivity of Carey Foster’s bridge is the same as the sensitivity of the Wheatstone bridge as it uses the same fundamental principle.
