Sleep Timer Setting [ SLEEP ] 1. Sleep Timer settings can also be configured
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 [ t r Ac E ] 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 [ b EEP ] 1. Key Sound settings can also be configured in
the Acaia apps. 2. Set the Key Sound function to on/off to enable/disable the
beeping sound.
Zero Range Setting [ 0 .r An GE ] 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 operation 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 setting whenever tare 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 the weighing result. However, zero operation does not
increase the scale capacity.
Weighing Filter Setting [ Fi l t ] 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
filter setting. 2. Press tare button to change the parameter.
Default Unit Setting [ Un i t ] 1. The Default Weighing Unit is set to grams
if [ 9 ] is selected and ounce if [ o 2 ] is selected.
Weighing Resolution Setting [ r ESo L ] 1. The default Weighing Resolution is
set to [ d EFAUL ]: the division is 0.1 g/0.002 oz. 2. Tap tare button to
switch the Weighing Resolution between [ d EFAUL ] and [ h i Gh ]. 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.

Bluetooth Setup Setting [ b t _ SEt ] 1. Off: Bluetooth disabled. The scale does not allow any Bluetooth connection. 2. On: Bluetooth enabled. The scale allows Bluetooth connection. The user may connect the scale with Acaia apps.
Battery Saving [ b At t SAv E ] 1. Save up to 20% of your battery by dimming the display after some time. It will return to its original brightness when the scale detects objects on it. 2. The number indicates the amount of time in seconds before the scale enters battery saving mode. 3. Tap the tare button to toggle through the options.
Pre-Infusion Time Out [ Pr E_ i n Fu ] 1.Determines when the scale times out in Auto-Start ( ) mode and two Auto-Start ( ) modes when the timer is manually started. This is most useful for long pre-infusion times and resolves the timeout that sometimes happens for slower pre-infusions. 2. The number indicates the time in seconds it will take for the scale to reset if no espresso flow or weight is detected.
14
Auto-Start Sensitivity [ SEn SE ] 1. Minimum weight is decreased for more
sensitivity. This is ideal for slower espresso shots in the modes. Stability
depends on environmental noise. The previous firmware started the timer at
~0.6 g into an espresso shot. 2. The number indicates the sensitivity of flow
detection in the modes. Smaller value indicates higher sensitivity, but is
recommended only for stable working environments.
Auto-Reset [ Au t o _ r ES ] 1. After a cup is removed, the timer will
automatically reset. This setting gives you options on how long to wait for
the reset. It enables the user to pull successive shots of espresso quickly in
the three Auto-Start modes. 2. The number indicates the timeout value in
seconds of timer reset after a cup is removed.
Reset to Default Setting [ r ESEt .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.
