This paper analyses the case study of Ohm's law of electric current in order to exhibit a novel approach to coordination between theory and measurement procedures. Ohm's scientific practice suggests that there are different 'layers' of constitution identifiable at different epistemic stages. His researches, in fact, involved several epistemic activities including instrument calibration, data reduction, measuring, experimental testing, and mathematical theorising. Some of the connections between these activities show how certain epistemic components had to be constituted, and thus integrated, within Ohm's empirical inquiry, rather than being ready-made features of the world to be used in his scientific reflection.
