Standard Resistance : There are 10 coils of .01 ohm each arranged on a rotary dial plus a circular slide wire of total resistance .01 ohm and 500 sub-divisions is equal to .00002ohms on the normal range. Multiplying Ratios : A single rotary switch furnishes 5 multiplying ratios of x100, x10, ×1, ×.01 and 0.1. Range of Measurement : The bridge has a range of 2 micro ohm to 11 ohm.Panel : A bakelite panel enclosed in a teak wood box is used. Separate current and potential terminals, battery and galvanometer terminals, push buttons for battery and galvanometer are provided on the panel.
Max. current : 10Aintermittently & 5 Acontinuously.Accuracy : ±0.5% current 5 Amps upto 10Amps
Coils : Managanin Coils are used. This bridge is very suitable for the use of wires & cable manufacturers. It is being extensively used for finding the resistance of transformer winding, contact resistance of relays etc.
