(I have a question after this long intro…)
Although the new Hario brew scale with a built in timer seems to be quite a hit with top specialty coffee roasters (Da Mateo and Johan & Nyström in Sweden sell it for example), I am a little unclear about the changing (decreasing) accuracy the more one weighs.
coffeegeek online offers an explanation: (and some praise)
"This scale packs a ton of innovation. It is accurate to 0.1g (accuracy is 1g over 200g, which Hario says was done for a fast scale readout). It has a maximum weight of 2kg, and has an automatic timer / count up function for brewing to very precise times and weights."
Now after that lengthy intro, comes my question, which I hope someone who knows will kindly answer: if one puts the over 200g (500-700g?) brew stand on that is meant for the scale, can one only expect to get an accuracy of 1g? Or does the accuracy go back to 0.1g again if one zeros out the scale? Even worse, when using an aeropress, one could be weighing 18g of coffee to an accuracy of 1g. Or again does the accuracy increase after zeroing out?
PS: I am hoping the answer is that the accuracy increases again after zeroing since in many other ways this seems like a great scale.
