Chapter 2: Getting Started

Preparation

• This scale is intended for indoor use.
• Select a work place that is stable, vibration-free, and, if possible, a horizontal location for the weighing platform.
• Do not locate the scale near any equipment/instrument which contains magnets.
• Avoid places where room temperatures are unstable. Room temperature above 40°C or below 15°C may result in weighing inaccuracy.

Installation

• To use an AC adapter instead of the built-in battery, plug the USB cable into the Micro-B USB port located on the back panel of the scale.
• Long press the Power button (⏻) to turn on the scale.
• It is highly recommended to calibrate the scale with calibration weight before using.
• Please make sure to use a heat resistant pad under hot objects.

Basic Operations

Modes

To Enable/Disable Modes, please go to Chapter 5: Configuration on Page 16.

• Mode 0 - Weighing Mode
• Mode 1 - Espresso Mode
• Mode 2 - Timer Mode
• Mode 3 - Auto Start Mode
• Mode 4 - Beverage Mode
• Mode 5 - Auto Tare Mode

Mode 0 - Weighing Mode

This mode displays weight. The LED display shows [ 0.0 ] when the weighing unit is in gram.

• There are two different weighing units in Weighing Mode: grams and ounces.
• The readability is 0.1g for grams and 0.005oz for ounces.

Mode 1 - Espresso Mode

The LED Timer is on the left, weighing result on the right.

• The timer displays from 0 to 59 seconds in cycle and will reset when reaching 60 seconds. When it resets, the Mode Indicator flashes.
• The readability decreases when the weight is over 99.9. The LED display shows up to a maximum of [1999].

To Enable/Disable Espresso Mode, please go to Chapter 5: Configuration on Page 16.

Mode 2 - Timer Mode

• The maximum time is 9 minutes and 59 seconds. The Weight display of the right side is from 0 to 999. When the value is over 1000, it will restart from 0 with Mode Indicator flashing.
• Mode indicator flashes to indicate 1000.

To Enable/Disable Timer Mode, please go to Chapter 5: Configuration on Page 16.

Mode 3 - Auto Start Mode

Place materials on the scale. Tap the Power button (⏻) to automatically tare. Begin pouring, and the timer will start with the pour. The timer stops when brewing equipment is removed.

To Enable/Disable Auto Start Mode, please go to Chapter 5: Configuration on Page 16.

Mode 4 - Beverage Mode

Follow instructions on the display to place the carafe, filter, and coffee (tap Tare in between steps). The timer will start with the pour. Lift dripper and filter off to stop the timer. The flashing number is your beverage weight with all items subtracted.

Display Meanings:

• As soon as weight is stabilized, the next step will show in the display.
• Timer starts when water pour is detected.
• Timer stops with a short press of ⏻ or when items (dripper) are removed.
• After the process, and the filter is removed, the display will blink/toggle the water weight and Beverage weight (marked with “b”).

To Enable/Disable Beverage Mode, please go to Chapter 5: Configuration on Page 16.

Mode 5 - Auto Tare Mode (after version 2.0.008)

Displays weight only. Place item on and off the scale, and it will automatically tare.

To Enable/Disable Auto Tare Mode, please go to Chapter 5: Configuration on Page 16.

Chapter 4: Calibration

Calibration Mode

1. While the scale is in Weighing Mode and the weighing unit is in gram, press the Tare button (T) quickly multiple times until the LED display shows [CAL] and then [500].
2. Place a 500g calibration weight on the scale and wait for the scale to execute the calibration procedure.
3. The LED display shows [-End-] when the calibration procedure is completed. You may unload the calibration weight when completed.

Note: Calibration weight of 100g, 1000g, 1500g, or 2000g can also be used.

Chapter 5: Configuration

Enter Settings

1. Press and hold the Power button (⏻) while turning ON the scale.
2. Keep the Power button (⏻) pressed. When the LED display shows [ACAI A] and turns [SEt], Long Press the Tare button (T) for another 2 seconds without releasing the button.
3. Release both Power (⏻) and Tare (T) buttons when the display shows [F.0000].
4. Long Press the Tare button (T) to move the flashing digit to the right. Repeat this step 4 times to enter Settings. It will show the first setting [SLEEP].

Detailed Settings Explanations

Auto Sleep Settings

Auto Sleep Settings can also be configured in the Acaia App. The number indicates the amount of time before the scale enters sleeping mode. For example, when 10 is selected, the scale enters sleeping mode after 10 minutes of idling.

Auto Zero Settings

1. When Auto Zero setting is off or disabled, the initial weight on the weighing pan must be less than 50% of capacity (i.e., less than 1kg for Acaia coffee scale) before the scale is turned on. Otherwise, an error [Er.303] occurs. When the error occurs, the scale would 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 regardless of whether the weight is over 50% of capacity.

Zero Tracking

Zero Tracking is a function for maintaining the zero indication within certain limits automatically.

• OFF: It is not recommended to turn off Zero Tracking because the zero indication would drift easily with room temperature changes.
• 0.5d~3d: For example, since each division is 0.1g, 3d = 0.3g. When Zero Tracking is set to 3d, any initial weight between +/- 0.3g on the weighing pan would be zeroed out.
• 2d is recommended in general for Acaia coffee scale.

Key Sound Settings

Key Sound Settings can also be configured in the Acaia App. Set the Key Sound function off to turn off the beeping sound or on to turn on the beeping sound.

Zero Range Setting

Zero Range setting determines the range for which the Tare button (T) executes zero operation instead of tare operation.

1. When Zero Range is set to 2, the range for zero-setting will be 2% of the capacity, i.e., +/- 40g for Acaia coffee scale. By pressing the Tare button (T), any weight within +/- 40g is zeroed out by zero operation, while any weight outside the range is tared out by tare operation.
2. If Zero Range is set to 100, the range for zero-setting will be 100% of the capacity, i.e., +/- 2kg for Acaia coffee scale. Therefore, instead of tare operation, zero operation would be executed in this setting whenever the Tare button (T) 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

The number shown on the LCD display indicates the current filter parameter which determines the speed for the load receptor to respond to weight and to determine the weighing value. The larger the number, the more stable but slower the weighing result will be.

Default Weighing Unit

The Default Weighing Unit is set to be gram.

Weighing resolution

1. The default Weighing Resolution is set to [Default]: the division is 0.1g under weight of 1000g and 0.5g from 1000g to 2000g.
2. When the Weighing Resolution is set to High, the division will be 0.1g throughout the entire time from 0g to 2000g.
