This aim is achieved in that the current modulation reference frequency (f17) in the data collector (12), which modulation reference frequency is subject to drift, is shifted by the instantaneous frequency difference (Δf) between the current transmitter-side reference frequency (f17) and the current transceiver-side reference frequency (f13). Thus, the current reference frequencies (f17 = f13) match in the case of the downlink without intervention in the measuring device (11) being required. Said frequency difference (Δf) in the data collector (12) is obtained from a comparison of the current receiver-side demodulation reference frequency (f16) with the current transmitter-side reference frequency (f17) and with the current transceiver-side reference frequency (f13) from telegrams (14, 21) from the transmitter (17) of the data collector (12) and from the transceiver (13) of the measuring device (11), which are received by means of the receiver (16) of the data collector (12). Without demand for the resources of the measuring device (11), all that is required therefor is merely the connection of a frequency-measuring comparator (20) before and after the demodulator (24) in the data collector (12), followed by a frequency subtractor (22) connected to the transmitter-side conditioner (19.17) in order to derive the reference frequency (f) from an oscillator frequency (F).
