High speed capture mode on less then three phases
When viewing the data for RMS values on individual phases on a three phase system or on any of the rms values on a single or split phase system when preforming high speed capture, the numbers will drift up and down due to the lack of a full waveform in the calculation.
If the signal is higher then 200 hz this should not be an issue as it will complete a full cycle within the sampling period. Due to the balanced nature of a three phase system the Sigma rms value of that system will give steady values either way.
