A measuring instrument whose measuring principle is based on an oscillator, for example an eddy counter, and in which there is arranged a sensor for recording a measured signal (S(t)), which can be supplied to an evaluation unit (2), characterized in that, from the phase increments psi(tau,t), that is to say from the differences between the instantaneous values phi(t) of the phase signal derived from the measured signal S(t) in a phase extractor (18) and values phi(t-tau) time- delayed by a delayed time tau, a coupling indicator value (KI) is formed in such a way that the existence of phase coupling with a further oscillator can be detected on the latter by means of comparison with a coupling reference value (KR).
