An automated temperature-controlled electrical DC voltage and resistance multiple reference standard (MRS) has been developed by Measurements International (MI) with the scientific support from Istituto Nazionale di Ricerca Metrologica (INRIM). The MRS includes a 10 V, 1 {\Omega}, k{\Omega} standards selectable via switch unit. This setup allows artifact calibration of high-end calibrators multimeters used in low-frequency measurements. two resistors are high-stability MI, while V is based...

Starting from 2019 a new central role is played by quantum standards, owing to the redefined SI, where electrical units are directly linked fundamental constants e (elementary charge) and h (Planck constant). Thus, metrologists nowadays trying extend astonishing accuracy attainable in dc measurements ac beyond, moving toward calibrations aiming voltage generation. Programmable Josephson Voltage Standards capable of fulfilling primary metrology requirements only for stepwise-approximated...
The voltage and current offsets of two typical precision operational amplifiers (OPAs) with BJT FET input, respectively, were continuously measured for years. paper presents the experiment, explains method data analysis, discusses results. long-term stability turns out to be limited mainly by random walk processes.
This paper reports about the realization of a pioneering system for pressure measurements, currently tested up to 400 kPa, based on Rayleigh scattering and with no mechanical parts interacting gas.The preliminary results showed that device exhibits strong linear dependence between gas scattered light, order 10 -5 , paving way promising innovative realizations scattering-based measurement single simple in wide range Pa 1 MPa.
Starting from 2019 a new central role is played by quantum standards, owing to the redefined SI [1], where electrical units are directly linked fundamental constants e (elementary charge) and h (Planck constant).Thus, metrologists nowadays trying extend astonishing accuracy attainable in dc measurements ac beyond, moving sinusoidal toward calibrations of arbitrary signals.Programmable Josephson Voltage Standards capable fulfilling primary metrology requirements only for signals up few...
Total joint arthroplasty bearings, which are most typically implanted in the human hip and knee, composed of ultra high molecular weight polyethylene (UHMWPE). However, bioactivity mechanical performance this polymer need improvement several efforts have been made with regard, order to extend material's service life expand its biomedical applications. In study, two distinct procedures for producing UHMWPE composites varying cellulose nanocrystal loadings were used (CNCs). The microstructure,...
At the National Institute of Metrological Research a convenient setup to verify DMMs linearity has been developed.It consists in top-class calibrated DC Voltage calibrator supplying directly under test.Some Keysight 3458A, Fluke 8508A and an 8588A are being enrolled tests.This is also compared with another Digital Analog Converter (R -2R DAC) place calibrator.The verified both when just switched on at thermal regime.The interference input stages connected parallel during measurements by...
