Product Description

 
Parameter Specification
Basic Structure Terminals for battery, galvanometer, current and potential terminals are all provided on the Bakelite panel enclosed in a teak wood box.
Range of Measurement The bridge has a range of 0.2 micro ohm to 110 ohms. Maximum Current: 10 amperes intermittently and 5 amperes continuously.
Accuracy ±0.05% + 1 small division of the slide wire.
Multiplying Ratios A rotary switch furnishes 5 multiplying ratios of ×100, ×10, ×1, ×0.1, and ×0.01.
Standard Resistance There are 10 coils of 0.01 ohm each arranged on a rotary dial plus a circular slide wire of total resistance 0.01 ohm and 500 sub-divisions. Each sub-division is equal to 0.00002 ohms on the normal range.
Current Reversing Switch A battery reversing switch is provided to reverse the current in the bridge to eliminate thermal effects.
