The scales on my Thermomix are not accurate - up to 30g out for larger quantities and up to 10 g out for smaller quantities.  This is particularly disconcerting for smaller quantities of butter and oil.  The feet of the machine are clean and it's on a level surface (I checked with a spirit level) The instruction manual does say that the scales aren't 100% accurate but this wasn't mentioned in the sales demos I went to
How can I minimise or get rid of the inaccuracy?
