GET STARTED
Congratulations on becoming the owner of our newly reimagined Acaia Pearl.
Like the classic Pearl that it is based on, this scale is tailored for coffee
enthusiasts and professionals alike. It has a longer battery life and helpful
brewing modes and includes new features such as a patent-pending technology
for faster-weighing response time, a brand new Flow-Rate Indicator for real-
time feedback during pour-over brewing, a modular design for sustainable
maintenance, and USB-C charging.
This quick start guide includes all the essential information you will need
for setting up and using your Pearl and to explore its more advanced features
if you wish to do so. You can stick to the basics by simply monitoring weight
and time as you brew, or use the Flow-Rate Indicator and additional brewing
modes to enrich your pour-over experience — the choice is yours and the
possibilities are endless.
Fall in love with the Pearl for the first time or all over again. Start
brewing today with consistency and insight.

Flow-Rate Indicator
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
flow rates. The indicator measures flow rates with lit LEDs starting from 0.5
g per second in the center to 9.5 g per second to the end. When the flow rate
exceeds 11.5 g per second, the last three LEDs will light up with enhanced
brightness, indicating a high flow rate.
To provide thresholds for ideal flow rates, the first pair of 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.
Battery Charging
You can use the included USB Type-C charger cable to connect the Pearl to a USB port for charging. Fully charged and with normal use, the scale can be used continuously for about 30-40 hours.
The Acaia Pearl is equipped with charging protection to avoid charging under high temperatures. It is normal if the scale does not charge when its surface is still hot from brewing coffee. Battery charging function will be enabled again when the scale has cooled.
Advanced Settings
The Acaia Pearl includes all the essential brewing modes to suit your coffee
brewing needs. Out-of-the-box settings include the most essential modes:
Weighing Only Mode/ Dual Display Mode. Explore and enable more brewing modes
with additional features such as auto-start, auto-tare, and beverage weight
calculation in Advanced Settings.
You can also tailor the scale according to your preference by changing the
system settings, such as adjusting the screen brightness, turning the Flow-
Rate Indicator on or off, and changing the auto-off timer setting.
To access Advanced Settings, press and hold while the LED display shows .
Continue holding until the battery level is displayed, the scale will then
enter the settings menu automatically.
See the next section for brewing modes that can be selected through Advanced Settings.
Brewing Modes at a Glance
Mode 1 – Weighing Only Mode
The weight-only mode for all weighing purposes. Press and hold T to select
gram or ounce as your weighing unit.
Mode 2 – Dual Display Mode
With dual display of timer and weight, this mode is made for all your coffee
brewing needs, with manual control for timer and tare functions.
Mode 3 – Pour Over Auto-Start Timer Mode ( ♦)
This mode is designed to aid pour-over coffee brewing. The scale will detect
the start of the flow from the kettle into the carafe and automatically start
the timer function; the timer stops when the brewing equipment has been
removed from the scale. When the carafe is removed from the scale, the display
flashes the final beverage weight.
Mode 4 – Portafilter Mode ( ■ )
This mode is designed to speed up the workflow of accurately weighing coffee
grounds in a portafilter. The scale automatically tares the portafilter and
allows adjustment of the ground coffee in the portafilter. The mode will reset
15 seconds after the portafilter has been removed to allow weighing for the
next shot.
Mode 5 – Beverage Mode
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, the total amount
of water added, beverage weight in the carafe, and the coffee-to-beverage
ratio at the end of the brew.

Calibrating Your Scale
The Acaia Pearl is a precision instrument, and regular calibration is recommended with frequent use. To perform a smart calibration, select Weighing Only Mode, switch the unit to grams, and follow the steps below:
Rapidly tap T until the screen displays .
Place a calibration weight on the center of the scale.
Calibration complete. Remove the weight.
Note: You may also use 500 g, 1000 g or 2000 g weights. If you use
weights other than Acaia Weights, we recommend F2 class standard calibration
weights.
Caution
– Do not place hot objects directly on the weighing pan. Use a heat-resistant
pad.

damage to scale.
– Avoid using the scale near very strong magnetic fields.
