 The measurement mode has to be changed to "Tapping", using either amplitude or phase of the lock-in 1 as source of the feedback.

 Note that only generator/lockin1 is relevant for tapping mode operation settings. Parameters "Excitation 2" and "Auxiliary frequency set" have no connection to it.

+When the frequency and amplitude are chosen, user needs to select the setpoint value. In case of amplitude based feedback it is always value lower than the actual one, in case of phase based feedback it should be also the case mostly. The same controls like in the case of [[contact|contact mode]] can be used to control the feedback loop. An example of feedback parameters when tapping mode is in operation are shown here:
