Upon regular use of your scale it is necessary to perform a calibration often. We recommend using F1 or F2 class calibration weights, like the 100 g weight that comes with the Acaia Lunar or the 500 g weights available at the Acaia online store.
Before calibrating your scale, we highly recommend checking the Acaia Updater or Pearl Updater to make sure that your scale has the latest firmware. All Acaia updater apps are available on both the Google Play Store and Apple App Store.
On the Acaia Pearl series and Lunar, it is possible to perform a quick, also known as smart, calibration.
You can purchase a certified calibration weight from our store here.
To perform a smart calibration:
- Find a quiet environment with a stable service with little background noise (i.e. a busy cafe with a lot of foot traffic could interfere with a calibration)
- Make sure your scale is in “weigh-only” mode. This mode displays the weight and nothing else, as “0.0”. You can switch modes by long-pressing the power button.
- Rapidly press the T button 6-7 times until the scale displays “CAL”. It will then display a number like “100” or “500”, but any F1 or F2 class weights that are 100, 300, 500, 1000, or 1500 grams will work. So, if it is displaying “500” but you only have a 100g weight, it is still good to use.
- Place your weight on the middle of the weighing surface until the calibration is complete.
