Vaiseshika Precision Vernier Potentiometer

we are offering vaiseshika precision vernier potentiometer. description
"vaiseshika" precision vernier potentiometer type - 9407 is designed for the measurement of voltage & current of a high order of accuracy. it can be used as a laboratory standard; for routine or accurate measurement of potential, resistance or current; as a standard for calibrating potentiometer; for standardizing electrical currents for electrical measuring instruments; and with thermocouples etc. excellent performance is achieved by the use of switches throughout the measuring circuit. a main switch divides the over all potential down to 0.1 v steps and the two successive 100 way switches divide down to 0.001 v and o.oooo1 v; a range switch multiplies the range by 1, 0.1 and 0.01 when required to achieve better resolution of measurement. these 100 way switches were specially designed for the potentiometer so that thermal e.m.f's generated at the contacts are minimized with low contact resistance. more over the circuit is designed to eliminate current flow through the 100 way switch contacts at balance, thus removing any error which might arise through changes in contact resistance
