A method for adjusting an output signal produced by a device under test from an input variable by: a) positioning the device under test at a first test device with a physical disturbance variable and a known input variable value, b) acquiring at least one measured value for the output signal, c) changing the adjustment state, d) acquiring a further measured value for the output signal, e) positioning the device under test at a further test device having a further disturbance variable value and the input variable value, f) acquiring a further measured value for the output signal, g) changing the adjustment state, h) acquiring a further measured value for the output signal, i) comparing the measured values acquired at the test devices for each adjustment state and determining a first adjustment state in which the correlation between the measured values is larger than in a second adjustment state.
