DESCRIPTION :
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 :10A intermittently & 5 A continuously.
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 resitance of transformer winding, contact resistance of relays etc. |
