2. OFF: It is not recommended to turn off zero tracking as the zero indication would drift easily as
the room temperature changes.
3. 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 would be zeroed out.
4. 1 d is recommended in general for Acaia coffee scale
Weighing resolution
