Claim:
1. A method for non-contact resistance measurement, comprising: providing a resistive element that is physically connected as part of a passive electrical circuit, the passive electrical circuit including an inductor connected in parallel with resistive element; without physically contacting the resistive element, using an electromagnetic field to produce an excitation in the passive electrical circuit, and determining a resistance of the resistive element based on an effect of said excitation on said electromagnetic field, wherein said determining includes evaluating said measurement relative to a plurality of further said measurements, each said further measurement corresponding to a respective further passive electrical circuit, wherein each said further passive electrical circuit has a respective known resistance connected in parallel with a further inductor having an inductance equal to that of said inductor, and wherein each said further passive electrical circuit is maintained, during the corresponding further measurement, in a predetermined positional relationship with the measurement device in order to calibrate a measurement arrangement.
