Abstract :
Load effect affect the accuracy of resistor measurements. The mathematical model of the load coefficients and the Least Square calculation method is discussed in this paper. A load coefficient measurement system is developed by using direct current comparator(DCC), extremely low load effect resistor standard and thermostatic apparatus. Examples is given to illustrate the measurement procedure and calculations. This measurement system can be used for correction of sampling resistor in electrical instruments, improving the accuracy of the instrument.
