Diagram of the Settings Menu

Dosing Speed [ SPEEd ]
You may adjust the dosing speed to prioritize either the accuracy or the speed of dosing. There are three speed settings available:

1. PrEC — Precision: Default speed, high accuracy. (default)
2. FASt — Fast: Faster speed, default accuracy (227 grams within 12 seconds); recommended for doses of 100 grams or more.
3. GrEEn — Green Bean: Default speed for green beans or light roast beans.

To save your selection and exit the settings sub-menu, press Dose. [ SPEEd ] will display on the LED to confirm that the selected option has been saved.

Zero Tracking Setting [ trAcE ]
Zero Tracking is a function to help compensate the weight readout fluctuations at zero point to improve the usability of the scale. The Acaia Orion Mini is allowed to compensate fluctuations by up to 2d according to industrial weighing guidelines.

1. Off: It is not recommended to turn off Zero Tracking; the zero indication can drift easily as the room temperature changes.
2. 0.5 d~3 d: For example, since each division is 0.1 g, 3 d = 0.3 g. When Zero Tracking is set to be 3 d, any initial weight between +/- 0.3 g on the weighing pan will be zeroed out.
3. 2 d is recommended in general for the Orion Mini.

To save your selection and exit the settings sub-menu, press Dose. [ trAcE ] will display on the LED to confirm that the selected option has been saved.
