Why is calibration important?

For this question, we recommend you to read our technical series, "Acaia University.”: https://acaia.co/blogs/news/acaia-university-why-is-calibration-important 

 

Calibration is important because it enables communication between collaborators - and with your future self.

It's possible to make good coffee with volumetric measurement, or even a scale that has gone out of calibration, thanks to the fact that coffee brewing is based around ratios. It's possible to make incredible coffee with even rudimentary tools. However, when it comes time to explain to someone else how to reproduce that exceptional coffee, having instruments that produce the same accurate measurements makes it much more likely that you'll be successful.

This doesn't just apply to telling another person how to reproduce the great cup of Yirgacheffe you just brewed. It also goes for you, in the future. If you've found a way to brew a coffee that you love, you'll want to be able to reproduce it a month later, no matter where you are and what equipment you end up using.

This is why we place such an emphasis on frequent calibration, and why it's so easy to calibrate the Pearl. All you need is a 500g calibration mass and a few minutes. Touch the T button repeatedly until the display reads "CAL 500", then place the mass on the scale. Performing this procedure any time you change work surfaces or location, or every few days if you always brew coffee in the same place, will help ensure that your delicious brews are reproducible.

  • (sorry, getting cut comment by sign protection) It is also stating e less or equal to 15mg at 500g; so a F2 (e 7.5g) or better weight class (F2-F1-E2-E1). This is the international OIML correct? In canada we use the american standard ASTM.. Am i correct assuming a 500g ASTM class 4 (e=10g) or better (class 3, ..2,1 or ultra class) is alright? Thanks you

  • Greetings, i followed the link and clicked on http://acaia.co/pages/calibration-for-acaia-scale Nice article but i wonder if 500g is recommended only for the Pearl or if the Lunar have a different preference? It is also stating e< or equal to 15mg @ 500g; so a F2 (e=7.5g) or better weight class (F2-F1-E2-E1). This is the international OIML correct? In canada we use the american standard ASTM.. Am i correct assuming a 500g ASTM class 4 (e=10g) or better (class 3, ..2,1 or ultra class) is alright? Would it be possible to upgrade the article for the American standard and Lunar info if different please, it is really informative on the calibration process and should even be on the front page for owners; it's really well done. Thanks you
