摘要

A temperature controlled 1Ω–10 kΩ Standard resistors setup was developed at National Institute of Metrological Research, (INRIM). The aim of this realization was the involvement of the setup resistors in the traceability transfer process to high accuracy multifunction electrical instruments used in Secondary Electrical Calibration Laboratories or even their use as primary Standards in high level Laboratories or Institutes. The 1Ω–10 kΩ Standards are formed respectively by two 10Ωand 100 kΩ parallel connected resistors nets inserted in a temperature controlled aluminium box. Construction details, temperature and power coefficients, stability data and preliminary mid-term use uncertainty budgets of the two setup Standards are given. Their first short time (2h) stability were on the order of few parts of 10–8. A test to calibrate a multifunction calibrator gave satisfactory results.
