Sleep Timer Setting [ SLEEP ]
1. Sleep Timer settings can also be congured in the Acaia apps.
2. The number indicates the amount of time before the scale automatically powers off. For example,
when 10 is selected, the scale powers off after 10 minutes of being idle if the scale is disconnected
from all mobile devices.
Zero Tracking Setting [ trAcE ]
1. Zero Tracking is a function for automatically maintaining the zero indication within certain limits.
2. OFF: It is not recommended to turn off Zero Tracking because the zero indication can drift easily
as the room temperature changes.
3. 0.5 d~3 d: For example, for standard resolution 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
gradually.
4. 2 d is recommended in general for the Acaia Lunar.
Key Sound Setting [ bEEP ]
1. Key Sound settings can also be congured in the Acaia apps.
2. Set the Key Sound function to on/off to enable/disable the beeping sound.
Zero Range Setting [ 0.rAnGE ]
1. The 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 Lunar. By pressing the tare button, any weight within +/- 40 g is zeroed out by zero opera-
tion while any weight that lies 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 Lunar. Therefore, instead of tare operation, zero operation would be executed in this set-
ting whenever tare button is pressed.
Notice: The difference between zero operation and tare operation is that zero operation would sim-
ply ignore the weight and display as 0 while tare operation would deduct the weight from the weigh-
ing result. However, zero operation does not increase the scale capacity.
Weighing Filter Setting [ Filt ]
1. The Weighing Filter Setting determines the speed at which the load receptor responds to weight
and determines the weighing value. The larger the number, the more stable but slower the weighing
result will be. The number shown on the LED display indicates the current lter setting.
2. Press tare button to change the parameter.
Default Unit Setting [ Unit ]
1. The Default Weighing Unit is set to grams if [ 9] is selected and ounce if [ o2 ] is selected.
Weighing Resolution Setting [ rESoL ]
1. The default Weighing Resolution is set to [ dEFAUL ]: the division is 0.1 g/0.002 oz.
2. Tap tare button to switch the Weighing Resolution between [ dEFAUL ] and [ hiGh ].
3. When the Weighing Resolution is set to high, division will be 0.01 g/0.0005 oz. The default display
will show [ 0.00 ] when the scale is set to grams, and [ 0.0000 ] for ounces in Weighing Mode.
Note: After setting Weighing Resolution to high, the default display will show [ 0:00 0.00 ] with timer
in Dual Display Mode and Auto Start Modes.

Weighing Only Mode Setting [ NoDE_1 ]
1. The default Weighing Only Mode Setting is set to ON, which means this mode is enabled.

1. By default, the Dual Display Mode Setting is set to ON, which means this mode is enabled.
• ON: The Dual Display Mode is enabled.
• OFF: The Dual Display Mode is disabled.
Timer Starts with Flow Mode Setting [ NodE_3 ]
1. By default, the Timer Starts with Flow Mode with Droplet Setting is set to ON, which means this
mode is enabled.
• ON: The Timer Starts with Flow Mode with Droplet is enabled.
• OFF: The Timer Starts with Flow Mode with Droplet is disabled.
Auto-Tare Timer Starts with Flow Mode Setting [ NodE_4 ]
1. The default Auto-Tare Timer Starts with Flow Mode with Droplet and Square Setting is set to
ON, which means this mode is enabled.
• ON: The Auto-Tare Timer Starts with Flow Mode with Droplet and Square is enabled.
• OFF: The Auto-Tare Timer Starts with Flow Mode with Droplet and Square is disabled.
Auto-Tare Auto-Start Timer Mode Setting [ NodE_5 ]
1. The default Auto-Tare Auto-Start Timer Mode with Triangle and Square Setting is set to ON,
which means this mode is enabled.
• ON: The Auto-Tare Auto-Start Timer Mode with Triangle and Square is enabled.
• OFF: The Auto-Tare Auto-Start Timer Mode with Triangle and Square is disabled.
Auto-Tare Mode Setting [ NodE_6 ]
1. The default Auto-Tare Mode with Square is set to ON, which means this mode is enabled.
• ON: The Auto-Tare Mode with Square is enabled.
• OFF: The Auto-Tare Mode with Square is disabled.
Bluetooth Setup Setting [ bt_SEt ]
1. OFF: Bluetooth is disabled. The scale does not allow any Bluetooth connection.
2. ON: Bluetooth is enabled. The scale allows Bluetooth connection. The user may connect the
scale with Acaia apps.
Battery Saving [ bAttSAvE ]
1. Save up to 20% of your battery by dimming the display after some time. It will return to its origi-
nal brightness when the scale detects objects on it.
2. The number indicates the amount of time before the scale enters battery saving mode.
3. Tap the tare button to toggle through the options.
Pre-Infusion Time Out [ PrE_inFu ]
1. Determines when the scale times out in all three of the Auto-Start modes. This is most useful
for long pre-infusion times and resolves the timeout that sometimes happens for slow pre-infusion
times.
2. The number indicates the time in seconds it will take for the scale to reset if no espresso ow or
weight is detected.
14

Auto-Start Sensitivity [ SEnSE ]
1. Minimum weight is decreased for more sensitivity. This is ideal for slower espresso shots in the
droplet icon modes. Stability depends on environmental noise. The previous rmware started the
timer at ~0.6 g into an espresso shot.
2. The number indicates the sensitivity of ow detection in the droplet icon modes. Smaller value
indicates higher sensitivity, but is recommended only for stable working environments.
Auto-Reset [ Auto_rES ]
1. After a cup is removed, the timer will automatically reset. This gives you options on how long to
wait for the reset. This setting enables the user to pull successive shots of espresso quickly in the
three Auto-Start modes.
2. The number indicates the timeout value of timer reset after a cup is removed.
Reset To Default Setting [ rESEt.d]
1. Select [ YES ] to reset all settings to default value.
2. Press and hold tare button for 1 second until [ SLEEP ] is shown on the LED to reset all settings
to default.
