The method involves initiating determination of a measurement quantity e.g. flow rate, by a measurement unit (2) from a transmission unit (3). A comparison signal is transferred from the transmission unit to the measurement unit. A comparison result produced by comparing the comparison signal with a stored signal. A measurement signal, which is generated following the quantity determination, is transferred from the measurement unit to the transmission unit, or the transmission unit is shifted into a defined state and an error signal is transferred to the transmission unit based on the result. An independent claim is also included for a transmitter. |
