SPECIFICATION
- To measure EMF by Crompton Potentiometer.
- To measure unknown resistance by Crompton Potentiometer.
- Crompton Potentiometer : Direct reading type, consisting of 7 coils and a circular slide wire. The scale is divided into 250 parts withpotential drop of 250 milli volts, Direct reading, with arrangement for stand arising with a standard cell, fine & course Rheostats are provided for adjusting the slide wire voltage. Range 0.001 to 1.75 volts.
- Digital Electronic D.C. Null Detector : In place of Galvanometer for better accuracy. Working Voltage:230 V AC ± 10% at 50 Hz.
- Digital Electronic Standard Cell Voltage output:1.018 Volts Accuracy:0.005% ± 1 digit with display. Working Voltage:230 V AC ± 10% at 50Hz.
- Potentiometer Power (2V/4V at 2Amp.) This gives fixed IC regulated outputs 2 and 4 Volt Supply DC at 2 Amp. with over load and short circuit protection.
- Cell Eliminator This is an Electronic Leclanche Cell works on 230V AC and gives regulated output of 1V5 DC. (Leclanche Cell 1V5)
- Potentiometer Wirewound potentio-meter mounted with three terminals 10 ohm 1 Watt.
- D.C.Ammeter 65mm round dial, mounted on bakelite stand, to read 0-100mA.
- Set of four unknown mounted on a board with terminals Resistance
- Standard resistence 20 ohms/1W
- Strongly supported by detailed Operating Instructions, giving details of Object, Theory, Design procedures, Report Suggestions and Book References.
