Sažetak
The past calibrations of the reference resistance standards of the Primary Electromagnetic Laboratory (PEL), the Leeds&Northrup (L&N) 1 ohm and 10 kohm standards, carried out over a period of more than thirty years, have been analysed. The least-squares fitting was used and the regression coefficients of up to the 3rd order polynomial were calculated and evaluated. Both standards have been maintaining into the self-developed oil ultrathermostat, where a stable temperature of 23 °C is maintained by the computer-based regulator within the limits of 10 mK. In the paper the analysis of the standards itself, as well as the achievement in the temperature regulation are described and pointed out.
