has been designed and fabricated to meet the precision calibration requirements. These Standard Resistors can be used for the calibration. To ensure stringent accuracy, high degree of stability and utmost reliability, the manganin wire and strips have been used to construct standard resistors. These standards incorporating the manganin coils which have been subjected to prolonged ageing and heat treatment, to improve stability and to reduce temperature coefficient. Joints are silver soldered with copper being used for connection to terminals. Resistance element is sealed in aluminium container having moisture free oil. Use of oil improves cooling effect which in turn imparts greater stability to resistance. For most accurate work the recommended wattage dissipation is 10 milli watts but upto 1 watt may be dissipated without harm to element.
