Mode Introduction

Weighing Only Mode

Mode 0 - Weighing Only Mode
In the Weighing Only Mode, the scale will only display weight in either grams or ounces.

• There are two different weighing units in Weighing Only Mode: gram and ounce. A dot will appear in the upper right of the LED display and the scale will read 0.000 when weighing in ounces.
• The readability is 0.1 g for grams and 0.005 oz for ounces.
• The LED display shows [0.0] when weighing in grams.

Espresso Mode

Mode 1 - Espresso Mode
Timer and weighing settings tailored for espresso use.

• This mode displays the LED timer on the left, and the weight on the right.
• The timer displays 0 to 59 seconds and will reset to 0 when 60 seconds has been reached. When it resets, the mode indicator flashes.
• When the weight exceeds 999 grams, the LED display only shows the integer part (the decimal point will not be displayed). The LED display shows up to 1999 grams. If the weight exceeds 1999 grams, the scale will display [ _ _ _ _ ].

Dual Display Mode

Mode 2 - Dual Display Mode
In Dual Display Mode, the scale displays [0.00 0] with a timer (left) and weight (right).

• There are two different weighing units in Dual Display Mode: gram and ounce.
• In grams, the LED display shows [0.00 0].
• In ounces, the LED display shows [0.00 0.00].
• The maximum display time will be 9 minutes and 59 seconds. The weight shown on the right side of the display measures from 0 to 999. When the value is over 1000, it will restart from 0 with mode indicator flashing.

Timer Starts with Flow Mode

Mode 3 -Timer Starts with Flow Mode
Place an item on the scale. Tap the power button to automatically tare and prepare the timer to detect the flow of water. The timer will flash, indicating that it is ready. Begin pouring and the timer will start with flow detection from the pour. The timer stops when the brewing equipment is removed.

• The LED display shows [0:00 0] with the timer on the left and the weight on the right in grams.
• The LED display shows [0:00 0.00] with the timer on the left and the weight on the right in ounces.
• The timer will display from [0:00] to [9:59] before stopping.

Beverage Mode

Mode 4 - Beverage Mode
Designed for pour overs and extraction measurements. Follow instructions on the display to place the carafe/cup, filter, and coffee (tap tare in between steps). The timer will start when the first flow of water is detected. Timer stops when the power button is tapped or items are removed (dripper). The flashing number is the beverage weight with all items subtracted.

• 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 display.
• After the process is completed and the filter is removed, the display will blink and flash between the water weight and beverage weight (marked with "b").

Portafilter Mode

Mode 5 - Portafilter Mode (for versions after 2.0.009)
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 [ Atr 0 ] before a portafilter is placed on the scale.
• In ounces, the display shows [ Atr 0.00 ] before a portafilter is placed on the scale.

Configuration

Enter Settings

1. With the Pearl powered off, press and hold the power button.
2. When the display shows [ ACAIA ] and then [ SEt ], continue to hold the power button and tap the tare button.
3. Release both power button and tare button when display shows [ F.0000 ].
4. Press and hold tare button to move the flashing digit to the right. Repeat this step for 4 times to enter Settings. It will show the first setting [ SLEEP ].

Settings Menu

Sleep Timer Setting [ SLEEP ]

1. The Sleep Timer setting can also be configured in the Acaia apps.
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.
3. Tap the tare button to toggle through the options.

Auto Zero Setting [ 0.AUto ]

1. When the Auto Zero function is off or disabled, the initial weight on the weighing pan must be less than 50% of capacity, i.e., less than 1 kg, before the scale is turned on; otherwise, an error [ Er.303 ] occurs. When the error occurs, the scale will not work until the initial weight on the weighing pan is cleared.
2. When Auto Zero setting is on or enabled, the scale displays the initial weight directly even if the weight is over 50% of capacity.

Zero Tracking Setting [ trAcE ]

1. 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 2 d according to the industrial weighing guidelines.
2. OFF: It is not recommended to turn off Zero Tracking as the zero indication would drift easily as the room temperature changes.
3. 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.
4. 2 d is recommended in general for Acaia coffee scales.

Key Sound Setting [ bEEP ]

1. Key Sound settings can also be configured in the Acaia apps.
2. Set the Key Sound function to on/off to turn the beeping sound on/off.

Zero Range Setting [ 0.rAnGE ]

1. 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 coffee scales. By pressing the tare button, any weight +/- 40 g is zeroed out by zero operation while any weight 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 coffee scales. Therefore, instead of tare operation, zero operation would be executed in this setting whenever the tare button is pressed.
4. Note: 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 [ Filt ]

1. The number shown on the LCD indicates the current filter parameter. The Weight Filter Setting determines the speed for the load receptor to respond to weight and to determine the weighing value. The higher the level, the more stable but slower the weighing result will be.
2. Press the tare button to change the parameter.

Default Weighing Unit Setting [ Unit ]

1. The Default Weighing Unit is set to grams if [ 9 ] is selected and ounce if [ o2 ] is selected.
2. Tap the tare button to switch the Default Weighing Unit between gram and ounce.

Weighing Resolution Setting [ rESoL ]

1. The default Weighing Resolution is set to [ dEFAUt ]; the division is 0.1 g for weights of 1000 g or less and 0.5 g for weights between 1000 g and 2000 g.
2. When the Weighing Resolution is set to high, the division will be 0.1 g throughout the entire time from 0 g to 2000 g.
3. Tap the tare button to switch the weighing resolution between [ dEFAUL ] and [ hiGh ].

Espresso Mode Setting [ NoDE_1 ]

1. The default Espresso Mode Setting is set to OFF, which means this mode is disabled.
2. ON: The Espresso Mode is enabled.
3. OFF: The Espresso Mode is disabled.
