CMI is the Czech national metrology institute with wide experience in electrical measurements. In its research programme CMI improves its measurement methods with a focus on improvement of traceability and on applicability for customer calibrations. CMI has been involved in several EMRP and EMPIR projects focused on metrology of electrical quantities, in some of them as Work Package leader. CMI developed and is operating digitally assisted and fully digital impedance bridges, together with calculable resistance and capacitance standards, covering the frequency range from audio frequencies up to over 1 MHz. Within the EMRP JRP AIM QuTE, a new fully digital four terminal pair bridge was developed. CMI will lead Work Package 2.
