We got some user feedback about the large size of the data file being created when the Power Profiler is sampling the current. This is due to un-compressed data stream being directly written on the PC. We are working on an on the fly non linear compression algorithm which is estimated to reduce the size of this data by 50x to 100x. Initial tests shows that the re-constructed samples are well within 1% of the least squares fit on the input samples. And they agree to the overall average value to less than 0.1%. Still in beta stage, but we would make a release with this feature in couple of weeks. Stay tuned.
Capturing a 5 minute recording in 42MByte file. That is close to 100x compression
