Sleep Timer Setting [ SLEEP ]
1. The Sleep Timer setting can also be congured in the Acaia apps.
2. The number displayed indicates the amount of time before the scale will automatically power
off. For example, when 10 is selected and the scale is disconnected from all mobile devices,
the scale will power off after 10 minutes of no use.
3. Tap the tare button to toggle through the options.
Auto Zero Setting [ 0.AUto ]
1. When the Auto Zero function is off or disabled, the initial weight on the weighing pan must be
less than 50% of capacity, i.e., less than 1 kg, before the scale is turned on; otherwise, an error
[ Er.303 ] occurs. When the error occurs, the scale will not work until the initial weight on the
weighing pan is cleared.
2. When Auto Zero setting is on or enabled, the scale displays the initial weight directly even if
the weight is over 50% of capacity.
Zero Tracking Setting [ trAcE ]
1. Zero Tracking is a function to help compensate the weight readout uctuations at zero point
to improve the usability of the scale. Acaia Pearl is allowed to compensate uctuations of up to
2 d according to the industrial weighing guidelines.
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. 2 d is recommended in general for Acaia coffee scales.
Key Sound Setting [ bEEP ]
1. Key Sound settings can also be congured in the Acaia apps.
2. Set the Key Sound function to on/off to turn the beeping sound on/off.
Zero Range Setting [ 0.rAnGE ]
1. Zero Range setting determines the range for which the tare button executes zero operation
instead of tare operation.
2. When Zero Range is set to 2, the range for zero setting will be 2% of the capacity, i.e., +/- 40
g for Acaia coffee scales. By pressing the tare button, any weight +/- 40 g is zeroed out by zero
operation while any weight outside the range is tared out by tare operation.
3. If Zero Range is set to 100, the range for zero-setting will be 100% of the capacity, i.e., +/- 2
kg for Acaia coffee scales. Therefore, instead of tare operation, zero operation would be exe-
cuted in this setting whenever the tare button is pressed.
4. Note: The difference between zero operation and tare operation is that zero operation would
simply ignore the weight and display as 0 while tare operation would deduct the weight from
the weighing result. However, zero operation does not increase the scale capacity.
Weighing Filter Setting [ Filt ]
1. The number shown on the LCD indicates the current lter parameter. The Weight Filter
Setting determines the speed for the load receptor to respond to weight and to determine the
weighing value. The higher the level, the more stable but slower the weighing result will be.
2. Press the tare button to change the parameter.
