outputting measurement values produced by the i-th amplifier unit from the i-th measurement signal; feeding at least two i-th reference signals (112, 113; 212, 213; 312, 313) to a further amplifier unit of the at least N+1 amplifier units; calibrating the further amplifier unit with the aid of the at least two i-th reference signals, wherein a zero point error and a gain error of the further amplifier unit are determined; adjusting the further amplifier unit if at least one of the errors determined for it is above a predetermined threshold value for said error; feeding the i-th measurement signal to the further amplifier unit; outputting measurement values produced by the further amplifier unit from the i-th measurement signal; feeding at least two reference signals to the i-th amplifier unit; calibrating the i-th amplifier unit with the aid of the at least two reference signals fed thereto, wherein a zero error and a gain error of the i-th amplifier unit are determined; and adjusting the i-th amplifier unit if at least one of the errors determined for it is above the predetermined threshold value for said error, characterised in that. after the step of feeding the i-th measurement signal to the further amplifier unit and before the step of outputting measurement values produced by the further amplifier unit from the i-th measurement signal, the method further comprises the step of copying filter coefficients and status storage areas of the at least one digital filter of the i-th amplifier unit to the at least one digital filter of the further amplifier unit, and after a step of feeding another measurement signal of the N measurement signals, which was previously fed to another amplifier unit of the at least N+1 amplifier units, to the i-th amplifier unit and before a step of outputting measurement values produced by the i-th amplifier unit from the other measurement signal, the method further comprises the step of copying filter coefficients and status storage areas of the at least one digital filter of the other amplifier unit to the at least one digital filter of the i-th amplifier unit. feeding an i-th measurement signal of the N measurement signals to an i-th amplifier unit of the at least N+1 amplifier units;
