Chapter 2: Getting Started
Preparation
This scale is intended for indoor use.
Select a work place that is stable, vibration-free and, if possible, a horizontal location for the
weighing platform.
Do not locate the scale near any equipment/instrument which contains magnets.
Avoid places where room temperatures are unstable. Room temperature above 40℃or below
15℃may result in weighing inaccuracy.

Chapter 4: Configuration 15

Auto Switch Off Setting [ SLEEP ]
Auto Sleep Settings can also be configured in the acaia APP.
1. The number indicates the amount of time before the scale enters sleeping mode. For example,
when 10 is selected, the scale enters sleeping mode after 10 minutes of idling.
2. Press button to toggle through the options.
3. Press and hold button for 1 second until the next setting, [ trAcE ], is shown on LED to
confirm the selected option.
Zero Tracking Setting [ trAcE ]
Zero Tracking is a function for maintaining the zero indication within certain limits automatically.
1. OFF: It is not recommended to turn off the Zero Tracking because the zero indication would
draft easily as room temperature changes.
2. 0.5d~3d: For example, for standard resolution each division is 0.1g, 3d = 0.3g. When Zero
Tracking is set to be 3d, any initial weight between +/- 0.3g on the weighing pan would be
zeroed out gradually.
3. 2d is recommended in general for acaia Lunar Coffee Scale.
4. Press and hold button for 1 second until the next setting, [ bEEP ], is shown on LED to
confirm the selected option.
Key Sound Setting [ bEEP ]
Key Sound Settings can also be configured in the acaia APP.
1. Set the Key Sound function off to turn off the beeping sound or on to turn on the beeping sound.
2. Press and hold button for 1 second until the next setting, [ bEEP ], is shown on LED to
confirm the selected option.
Chapter 4: Configuration 16

Zero Range Setting [ 0.rAnGE ]
Zero Range setting determines the range for which button executes zero operation instead of
tare operation.
1. When Zero Range is set to 2, the range for zero-setting will be 2% of the capacity, i.e., +/- 40g
for acaia Lunar Coffee Scale. By pressing button, any weight within +/- 40g is zeroed out by
zero operation while any weight lays outside the range is tared out by tare operation.
2. If Zero Range is set to 100, the range for zero-setting will be 100% of the capacity, i.e., +/- 2kg
for acaia Lunar Coffee Scale. Therefore, instead of tare operation, zero operation would be
executed in this setting whenever button is pressed.
Notice: 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
weighing result. However, zero operation does not increase the scale capacity.
Weighing Filter Setting [ Filt. ]
1. The number shown on LED display indicates the current filter parameter which determines the
speed for load receptor to response to weight and to determine the weighing value. The larger
the number, the more stable but slower the weighing result will be.
2. Press button to change the parameter.
3. Press and hold button for 1 second until the next setting, [ Unit ] is shown on the LED to
confirm the selected parameter.
Default Unit Setting [ Unit ]
1. The Default Weighing Unit is set to be gram if [ 9] is selected and ounce if [ o2 ] is
selected.
2. Press button to switch the Default Weighing Unit between gram and ounce.
3. Press and hold button for 1 second until [ rESoL ] is shown on LED to confirm the selected
option.
Chapter 4: Configuration 17

Weighing Resolution Setting [ rESoL ]
1. The default Weighing Resolution is set to [ dEFAUL ]: the division is 0.1g / 0.02oz.
2. Pressbutton to switch the weighing resolution between [ dEFAUL ] and [ hiGh ].
3. When the Weighing Resolution is set to high, division will be 0.01g/0.0005oz. The default
display will show [ 0.00 ] in Weighing Mode.
4. Press and hold button for 1 second until [ rESEt.d] is shown on LED to confirm the
selected option.
Note : After setting Weighing Resolution to high, the default display will show [0:00 0.00] with timer
in Dual Mode and Auto Start Mode.
Reset Password Setting [ rESEt.d]
1. Select [ YES ] to clear the bluetooth connection password.
2. Press and hold button for 1 second until [ bt_SEt ] is shown on LED to clear the password.
Bluetooth Setup Setting [ bt_SEt ]
1. OFF: The bluetooth is disabled. The scale does not allow any bluetooth connection.
2. on: The bluetooth is enabled. The scale allows bluetooth connection. User may connect the
scale with acaia APPs.

Appendix A. Smart-Calibration
If you decide to calibrate your scale, it will only be as good as the accuracy of the calibration
weights you use.
*Note : We recommend standard weights with class F1or F2.
Calibration Mode
1. While the scale is in Weighing Mode and the weighing unit is in gram, press button quickly
multiple times until LED display shows [ CAL ] and then [ 500.00 ].
2. Place acaia 100g weight on scale and wait for the scale to execute calibration procedure.
3. The LED display shows [ _End_ ] when the calibration procedure is completed. You may
unload the calibration weight when completed.
Note: If you use weights other than acaia Weights, we recommend standard weights with 100g*n.
For example, 500g or 1000g.
