I'm still waiting for a few items to turn up, before I can start assembling, but in the meantime I have been studying all the Ispindel discussion on this and other forums, plus Github - there is a tremendous amount.
Despite all my reading, I remain confused by the formulae and how to make use of it. Has anyone found a good clear explanation (idiots guide) of how to use the formula? I have seen and downloaded the Excel spreadsheet calculator. I am especially confused by 'tilt', which seems to be a part of the formula - are the 'tilt' intended to be replaced with a single variable?
EDIT - This is the default formula in the spreadsheet, exactly as downloaded....
-0.050364959*tilt^2 + 6.868698667*tilt - 185.8498673 |
Am I supposed to enter my own figures in the sheet, from my calibration tests at each SG reference point, then replace 'tilt' in the above with my initial calibration figure of the Ispindel angle in plain water?
