- Abstract:
- In the Primary Electromagnetic Laboratory (PEL), which is a part of the Faculty of Electrical Engineering and Computing of the University of Zagreb and a part of the Croatian metrology system, the unit of resistance (ohm) is maintained by the group of reference and working standards of nominal decade values ranging from 1 mΩ to 100 GΩ. The group of high value resistance standards from 100 MΩ to 100 GΩ is the hindmost incorporated in the resistance traceability chain, and relies on laboratory developed measurement system for high resistance comparison, which is presented in this paper. Realization of traceability of high value resistance standard group toward both of 10 kΩ and 10 MΩ reference standards is described. Based on 10 MΩ as starting point, the high resistance scaling was performed and temperature coefficients of resistors were determined. The achieved results of high value resistance comparison were analyzed and compared with the calibration values obtained at Physikalisch-Technische Bundesanstalt (PTB).
