The main dial setting is kept nearly equal to the emf being measured. The third dial is obtained from a shunt circuit which permits a true zero and a small negative setting to be obtained. Number potsntiometer Employees Upto 10 People. Rust proof body Durability Easy to operate Specification: This potentiometer is provided with an independent standardising circuit AD which can be set on any range of standard cell emf from 1. The value of the compensating resistors is such that the resistance of the potentiometer circuit, as viewed from terminals, where the unknown emf is applied, remains constant irrespective of the position of the sliding contacts. There is one dial switch with fifteen steps, each having a precision resistor. Now letвЂ™s think about another circuit, where a battery is connected across a resistor via a switch and a rheostat as shown in the figure below. The potentiometer is used to monitor the value of temperature where a thermocouple is employed.

This textbook вЂќ Electrical and Electronics Measurements by S. Measurements are subject to stray thermal crmpton contact Potntiometer s in the potentiometergalvanometer and the measuring circuits. Hence, voltage drop per unit length of the resistor is equal throughout its length. This provides a means of standard cell balance resistance to suit the emf value of the particular standard cell used. To fulfill potentiomdter diversified demands of our clients, we offer these products at budget friendly prices. The measuring circuit current I cromptno must be equal to 10 mA in order to produce a voltage drop of 1. There is also a single turn circular slide wire. This potentiometer is supplied with a self standardization circuit built in, which renders The switch S is thrown to the calibrate position and the galvanometer key is tapped while the rheostat is adjusted for zero deflection on the galvanometer. DC CromptonвЂ™s Potentiometer or Laboratory Type Potentiometer In this potentiometer, only one or two main dials, consisting of decade resistance boxes, are used. The following steps are used when making measurements with the above potentiometer: As the balance is approached, the protective resistance is shorted, and final adjustments are made to obtain true balance. This does not mean, unfortunately, that small voltages can be read with assurance to 0. The circuit of a single potentiometer may be modified in a simple way to add a second range, which is usually by a second factor, such as 0. This fixes the working current to its proper value.

Thus, these products are widely used in diverse sectors such as laboratories, health care sector and medical institutions. These EMFs can be crompgon only by special construction i.
