Adjustable heavy Duty D.C. Current Source

It is a useful and economical substitute for a D.C. battery. The unit is mains operated and can deliver a continuously adjustable D.C. current of 0 to 10 amperes maximum.The unit consists of a variac a step down transformer, a bridge rectifier, filter circuit and an ammeter of 0 to 10 amperes to read current.

Conductivity Attachement

It is an an arrangement to hold specimens in the form of wires, rods, strips etc. Separate current and potential terminals are provided. Distance between potential points is 500 mms. It can hold speciments of any size between 1/2" dia to 42 S.W.G. wires.

COMPONENTS TO BE USED

Oxford Spot Reflecting Galvanometer Cat. No. 1701It is a sensitive null detecter to be used with the Kelvin Double Bridge. It is mains operated instrument with a built-in lamp and scale arrangement. The moving coil can be locked or set free accordingly as the instrument is in transit or in use.There is a zero adjusting knob also.A universal sensitivity reducing shunt is also built in.


FEATURES


General

This bridge is very suitable for the use of wires and cables manufactures. It is being extensively used for finding the reistance of transformer windings, contact resistance of relays etc.

Standard Resistance

There are 10 coils of 0.01 Ohm each arranged on a rotary dial plus a circular slidewire of total resistance 0.01 Ohm and 500 sub-division. Each sub-division is equal to 0.00002 Ohms on the normal range.

Multiplying Ratio

A rotary switch furnishes 5 multiplying ratios of x 100, x 10, x 1, x 0.1 and x 0.01Range of Measurement: The bridge has a range of 0.2 micro ohm to 11ohms
