Information on the sampling rate of the ION6200
All released meter firmware
The sampling rate of the ION 6200 is 64 samples/cycle. With this sampling rate, the meter should be able to calculate harmonics up the 31st harmonic.
However, for the THD calculation, only the first harmonics are taken into account; this has been verified with firmware.
In addition, the ION 6200 is a blind cycle meter which means that...since the meter takes 64 samples per cycle, it actually uses all 64 samples to calculate the data.
These samples are locked to the frequency of V1.
