Just as i little heads up : Saris H3 Discussion/Issues](Saris H3 Discussion/Issues - #844 by PaulJones
Ive since read on various forums about how the 10Kg calibration “could be beneficial” although couldn’t find it in any Avio’s (lack of) documentation.
I’d say this is part of an essential routine & ill be doing it every week while I’m still using the Avio (although its days are very numbered).
