(0.04%) Primarily, these low resistance standards or shunts are used in accurate measurements of large currents by the potentiometric method. They may be used as comparison standards by either the adjustable ratio Kelvin Bridge or the potentiometric method. The normal resistance is that as measured between the potential contracts. The shunts have been designed to provide ample radiating surface for operation in air at ordinary room temperature at their rated current carrying capacities. A resistor of this type may be used in place of a Reichsanstalt type if a +/- 0.04% limit of error is satisfactory. The SR-15 (illustrated), SR-100 and SR-300 resistors consist of a continuous strip of one or more folds of a resistive material held in position by spacers. LOW VALUE RESISTANCE STANDARD
