Measurement device, such as a mass flow meter, operates in that an output value, or measurement, is produced as a function of an input value. In a self-test, different known input values can be applied to the meter and corresponding output values measured. If the measured output value is different from the expected output value by greater than a threshold value a fault condition is indicated. An Independent claim is made for a corresponding method for testing the operation of a mass flow meter. |
