r.m.s. value of integer cycles (CVrms)
In the measurement interval, cycles passing through the level set by the auto
measurement parameter (Level) are found. The r.m.s. value of these integer cycles is
measured.
Mean value of integer cycles (CVmean)
In the measurement interval, cycles passing through the level set by the auto
measurement parameter (Level) are found. The mean value of these integer cycles is
measured.
The following parameter can be selected.
Level A cycle between the maximum value (
+
Peak) and minimum value
(
−
Peak) of the waveform data in the measurement interval is
determined to 100%. Cycles from the point where Level crosses the
waveform data are found. The r.m.s. value or mean value of the
found cycles is calculated. The setting range of this Level is 10% to
90%.
Example of measurement :
If Level is set as shown in the following Fig., the r.m.s. value or mean value of
between the measurement start and measurement end points is measured.
