Product Care Information

Battery Charge
You can charge the battery by plugging the USB Type-C cable into any of the power supplies listed below:

• A computer
• A USB wall-charger with an output of 5 volts and 1 amp
• A USB-C PD charger supporting 5 volts
• A DC car-charger with an output of 5 volts and 1 amp

  

• 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.
  * Note: The Acaia Pearl is equipped with charging protection to prevent the battery from charging under high temperatures. It is normal if the scale does not charge when the surface is hot from brewing coffee. Battery charging function will be enabled once the scale has cooled.

Battery Indicator

Press and hold the Power button while the LED display shows [ ACAIA ] and then changes to [ SEt ]. Continue to hold the Power button until the battery percentage is displayed.

Calibration

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 at both ends. 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 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.

When the vessel is removed from the scale, the display flashes the final beverage weight.

• In grams, the LED display shows [ 0:00 0.0 ] with the timer on the left and the weight on the right.

Mode 4 – Portafilter Mode

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.

• In grams, the display shows [ 0.0 ] before a portafilter is placed on the scale.
• In ounces, the display shows [ 0.000 ] before a portafilter is placed on the scale.

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, total amount of water added, beverage weight in the carafe, and the coffee-to-beverage ratio at the end of the brew.

• 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.

Settings Menu

• Sleep Timer Setting [ SLEEP ]
  • The default setting is 5 minutes.
  • 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 ]
  • The default setting is 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 ]
  • The default setting is 90 seconds.
  • The scale will wait for the selected number of seconds to enter Battery Saving Mode. The LED display will dim to save power.
• Zero Tracking Setting [ trAcE ]
  • The default Zero Tracking is set to 2 d.
  • Zero Tracking is a function to help compensate the weight readout fluctuations at zero point 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.
  • Off: It is not recommended to turn off Zero Tracking as the zero indication can drift easily as the room temperature changes.
  •  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.
  •  d is recommended in general for Acaia Pearl.
• Key Sound Setting [ bEEP ]
  • The default setting is On.
  • Use this setting to turn the beeping sound on or off.
