• It takes about 1-2 hours to fully charge the battery when the battery is empty. Try not to
let the battery completely run out before charging. Charge the battery as needed.
• A fully charged battery can work continuously for about 30 hours.
• Remaining battery power can be viewed when the scale is off by pressing and holding the
Power button until the Battery Indicator comes on. You can also check the battery power by
connecting the scale to Acaia Apps.

Flow-Rate Indicator
6
The Flow-Rate Indicator is an LED bar on the top of the display. It helps you visualize your
pouring speed in real time and suggests thresholds for ideal ow rates. The indicator measures
ow rates with lit LEDs starting from 0.5 g per second in the center to 9.5 g per second at both
ends. When the ow rate exceeds 11.5 g per second, the last three LEDs will light up with
enhanced brightness, indicating a high ow rate.
To provide thresholds for ideal ow rates, the rst pair of the brighter LEDs represents 2.5 g per
second. The second pair of brighter LEDs represents 6.5 g per second, for targeting a faster
pouring speed.
The Flow-Rate Indicator can be activated in Dual Display Mode, Pour Over Auto-Start Timer
Mode, and Beverage Mode. You can turn the indicator on or off in the advanced settings menu.
Flow Rate > 2.5 g/s Flow Rate > 6.5 g/s Flow Rate > 11.5 g/s

Action Operation
Tare Weight Tap Tare button
Reset Mode Double tap Tare button
Switch Mode Press and hold Power button
The Portafilter Mode is designed to simplify the workflow
of weighing coffee grounds in a portafilter. The scale
automatically detects a portafilter or other vessel and
tares the weight of the vessel. Remove the portafilter to
add coffee grounds, then place on the scale again to
measure the weight of the coffee grounds. Repeat as needed to adjust the weight. After
the portafilter has been removed for 15 seconds, the scale will reset the mode to default
for the next workflow.

• There are two different weighing units in Beverage Mode: gram and ounce.
• As soon as the weight is stabilized or the tare button is pressed, the next step will show in
the display.“---” indicates the scale is performing auto-tare.
• AFTER the process is completed and the filter is removed, the display will blink and flash
the time elapsed for the brew, total amount of water added, beverage weight in the carafe,
and the coffee-to-beverage ratio at the end of the brew.

This mode is designed to measure the coffee-to-beverage
ratio. It is one of the most consistent methods for measuring
pour over extraction. With this mode, you will be able to see
the time elapsed for the brew, total amount of water added,
beverage weight in the carafe, and the coffee-to-beverage
ratio at the end of the brew.

Sleep Timer Setting [ SLEEP ]
1. The default setting is 5 minutes.
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.
Brightness Setting [ bright ]
1. The default setting is 2.
2. You can adjust the brightness of the LED display. Set to 4 when operating under strong light,
such as when outdoors.
Battery Saving Setting [ bAttSAvE ]
1. The default setting is 90 seconds.
2. The scale will wait for the selected number of seconds to enter Battery Saving Mode.

Zero Tracking Setting [ trAcE ]
1. The default Zero Tracking is set to 2 d.

to improve the usability of the scale. Acaia Pearl is allowed to compensate fluctuations of up
to 3 d according to the industrial weighing guidelines.
3. Off: It is not recommended to turn off Zero Tracking as the zero indication can drift easily as
the room temperature changes.
4. 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.
5. 2 d is recommended in general for Acaia Pearl.
Key Sound Setting [ bEEP ]
1. The default setting is On.
2. Use this setting to turn the beeping sound on or off.
Weighing Filter Setting [ FiLtEr ]
