“…Fluke 5700 A of the INRIM-Lab by means of an automated measurement system. This MFC is in turn calibrated vs. the reference standards of the same laboratory, also involving the system described in [3]. The DMM had been tested for a period of six months without performing an adjustment to evaluate its time stability vs. its specifications.…”

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.

At the National Institute of Metrological Research a convenient setup to verify the DMMs linearity has been developed. It consists in a top-class calibrated DC Voltage calibrator supplying directly the DMMs under test. Some Keysight 3458A, a Fluke 8508A and an 8588A DMMs are being enrolled in the tests. This setup is also compared with another setup with a Digital Analog Converter (R -2R DAC) in place of the calibrator. The DMMs linearity is being verified both when DMMs are just switched on and at thermal regime. The interference of the input stages of the DMMs connected in parallel during the linearity measurements and the linearity by inverting the plug of one of the DMMs connected in parallel are currently under verification.
