Sažetak
The main task of national laboratory for electrical measurements in Croatia (ETF-PEL) is to ensure a system of international traceability for the basic electromagnetic standards. Traceability of primary resistance standards in Croatia is achieved through comparisons with PTB primary resistance standards using our 1 W and 10 kW standards. We established traceability chain for the rest of our standards in our laboratory. The methods for comparing standards [1, 2], and a method of calibrating DMMs [3] have been already published. Determination of DMM error has to be done for any combination of voltages applied to resistors, since there is different correction for different voltages. If we keep the same voltages on different resistance standards, in order to reduce DMM calibration runs, we have different power dissipation in each case. For high precision measurements of standard resistors load coefficients (RLC) have to be measured. In this paper we present a method of obtaining RLCs suitable when standard resistors are compared with digital multimeter (DMM).
