Usage                                 : It is a precision bridge for the measurement of low resistance.

Basic Structure                 : A Bakelite panel enclosed in a teak wood box is used. Separate current and potential terminals, push buttons for battery and galvanometer                                 terminals

Range of Measurement : 1.1 to 0.00002 ohms.

Maximum Current      : 2 Amperes.

Accuracy                              : + 0.1%.

Multiplying Ratios : A single rotary switch furnishes 3 multiplying ratios of x1, x0.1 and x0.01.

Standard Resistance     : 10 coils of 0.1 ohm each are arranged on a rotary dial and a circular slide wire of total resistance 0.1 ohm and of 500 sub-divisions is                                             equal to 0.0002 ohm on the normal range.
