Confronto di misura di alto livello fra l’INRIM ed un laboratorio elettrico su di un calibratore di elevata accuratezza

An accurate comparison measurement between INRIM and a high-level secondary calibration laboratory has been performed with satisfactory results. The used instrument was a multifunction calibrator for its wide measurement range and excellent definability for whose very small calibration uncertainties are needed. The calibrator resulted eligible to check properly the measurement capability of electrical high level secondary Laboratories
