:When OFF is selected and the next measurement value is not determined within the waiting time
period, the frequency or the rotation speed will be determined using the value which is calculated
based on the time period between the timing of the last measurement and the timing of the sampling.
Put it to 0 when the measurement value is below the fixed value.
