1. Method for operating a Coriolis mass flowmeter (1) having at least one measuring tube (2), an oscillation exciting device (3) for exciting the measuring tube (2) to an oscillation (4), at least a first oscillation sensor (5) and a second oscillation sensor (6) and at least a first sensor signal path and a second sensor signal path,characterized inthat at least one first test signal is generated having at least one first test signal frequency,that the at least first test signal is fed at least into the first sensor signal path and into the second sensor signal path,that the at least first test signal is guided by the first sensor signal path over the first oscillation sensor (5) and by the second sensor signal path over the second oscillation sensor (6),that a test signal propagation time difference of at least the first test signal is determined at least between the first sensor signal path and the second sensor signal path, andthat a sensor signal propagation time difference between a first sensor signal and a second sensor signal is compensated with the test signal propagation time difference.
