This instrument gives an accurate measurement of resistance and
also
locates faults in cables by adopting the murray and varley loop circuit test. Complete with Galvanometer. The
instrument is
provided with another switch controlling the sensitivity or short circuiting the Galvanometer.
Arrangements are provided to
use an extra galvo or high source voltage. Ration arms of the bridge are capable of
selecting and multiplying factors of
.001, .01, .1, 10, 100 and 1000 for conductive resistance measurements and for
Varley loops sets and capable of selecting
multiplying factors of 10, 100, 1000 for Murray test. Coils of Manganin
wire, Accuracy of Coils : 0.05%.
