    CHAPTER 4. MEASUREMENT SETUP 4.2 Measurement interval The measurement interval is the time during which data is taken. The fundamental frequency of the measured signals restricts the measurement intervals that yield meaningful results. For example, measuring 10Hz with an interval of less than the 0.5s setting will not yield stable results. The unit needs a number of cycles to be present to determine the frequency, and measurement intervals are not synchronized to the input.
