View ArticleCalibration and accuracy with 2.72.
With a new Quad Rev 2.72 I am getting VERY bad voltage accuracy – off by 10%-20%, even after calibration (not perfect calibration, I don’t have all the voltages – but close). It is reading off when the...

I suspect when the PAWN 11 'fails' to load, it is the last records that are not getting picked up correctly. So most of the code may be OK but I wouldn't necessarily trust it to be completely right. If...
