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 100g weight that comes with the Acaia Lunar or the 500g weights available at the Acaia online store.
On the Acaia Pearl and Lunar, it is possible to perform a quick 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.
