A method for accurately acquiring multiple analog input signals that are converted using a plurality of A/D converters into corresponding digital single measured values. A first measurement averaging cycle having a predetermined total number of measuring intervals is predetermined by a higher-order control unit. First and second input signals are acquired by first and second A/D converters in a first and second number of measuring intervals, the second number being smaller than the first number. The first and second input signals are averaged to form first and second measured values, respectively. The first input signal is acquired by the second A/D converter in a third number of measuring intervals as at least one further single measured value. A message is output if a deviation of the at least one further single measured value from a single measured value of the first input signals measured by the first A/D converter or from the first measured values averaged up to that point exceeds a maximum permissible absolute value of the deviation.
