“…The INRIM-Lab verified the DMM using the measurement procedures approved by INRIM as a signatory of the CIPM MRA 1 and supported by approved CMCs. In addition, in DC Voltage, the DMM was also compared with a recently built high precision High DC Voltage Standard [4].…”

A metrological verification of a high precision digital multimeter was made by the laboratory of calibration of programmable electrical multifunction instruments of the National Institute of Metrological Research (INRIM) in order to verify its accuracy and stability. The instrument had been tested for a period of six months for five low-frequency electrical quantities (DC and AC Voltage and Current and DC Resistance). Its stability and precision were compared with the accuracy specifications of the manufacturer. As a new approach, a performance index of the DMM was introduced and evaluated for each examined measurement point. The DMM showed a satisfactory agreement with its specifications to be considered at the level of other top-class DMMs and even better in some measurements points.

“…These performance values were evaluated taking into account ∆ fin−first instead of ∆ max -abs as the declared accuracy in these points is presumably too small 4. These performance values were evaluated taking into account ∆ fin−first instead of ∆ max -abs as presumably a systematic error in the DMM adjustment process happened.…”

“…In addition, this result is a further demonstration that international agreements such as the CIPM MRA or the EA MLA 5 are correctly implemented. Future aim of the collaboration between INRIM and ESA could be an ILC involving as traveling Standard a DC Voltage high accuracy multi-value transportable Standard developed at INRIM [14].…”

Inter-laboratory comparisons (ILCs) are an effective mean to establish the compatibility of the measurements among laboratories also belonging to different countries and so belonging to different measurement systems. As consequence, they are a mean to assure confidence in the competence and in the correctness of the unit dissemination processes from national Standards in different countries. This paper refers on an ILC between the National Institute of Metrological Research (INRIM-Italy) and the European space research and technology Centre (ESA-ESTEC), belonging therefore to two different measurement systems, on DC Voltage, DC Resistance and Electrical Capacitance carried out in 2016. The comparison had satisfactory results.
