However, stable readings are not necessarily correct; harmonic distortion can cause erroneous yet stable readings. Sine
wave signals with much harmonic distortion, see Fig. 3-17, can be measured correctly by shifting the trigger point to a
suitable level or by using continuously variable sensitivity, see Fig. 3-16. You can also use Trigger Hold-Off, in case the
measurement result is not in line with your expectations.
