Care and Cleaning

• Use a soft cloth with warm water only to clean the product.
• Do not use detergent or other chemicals for cleaning and soaking as it can damage the anodized coating on the product.

Tare Save

If you have a frequently used container in your weighing workflow, you can save the weight of the container using the Tare Save function. This will allow you to weigh the container with contents, then trigger Tare Save to deduct the container weight and obtain the net weight. The Tare Save function can be activated in Weighing mode and Dual Display Mode.

Save Container Weight

1. Place a container on the scale.
2. Press and hold Tare button for 2 seconds when reading is stable. The weight is stored as a preset container weight.
3. You may continue using your scale.

Tare Container Weight Using Tare Save

1. Place a container along with its contents on the scale.
2. Press and hold Tare button for 0.5 second. The scale will display the weight to be deducted.
3. The net weight is displayed on the scale.

• To save a new container weight, place the desired container on the scale, then press and hold Tare button for 2 seconds. This will register a new preset container weight.
• It is only allowed to tare container weight once, if you press and hold Tare button for 0.5 second again, the scale will display [ CUP ] and the preset container weight, but the cointainer weight will not be tared again.

Configuration

Enter Settings

1. With the Lunar powered off, press and hold the Power button. When the LED display shows [ ACAIA ] and then changes to [ SEt ], release the Power button.
2. Tap T button to enter Settings. The first setting is [ SLEEP ].
3.  Please refer to the following table for key operations

   Next Setting| Tap Tare button
   Enter Setting| Press and hold Tare button
   Toggle Options| Tap Tare button
   Save Option| Press and hold Tare button
   Back to Menu Without Saving| Tap Power button

Settings Menu

Sleep Timer Setting [ SLEEP ]

1. Sleep Timer settings can also be configured in the Acaia apps.
2. The number indicates the amount of time before the scale automatically powers off. For example, when 10 is selected, the scale powers off after 10 minutes of being idle if the scale is disconnected from all mobile devices.

Zero Tracking Setting [ trAcE ]

1. Zero Tracking is a function for automatically maintaining the zero indication within certain limits.
2. Off: It is not recommended to turn off Zero Tracking because the zero indication can drift easily as the room temperature changes.
3. 0.5 d~3 d: For example, for standard resolution 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 will be zeroed out gradually.
4. 2 d is recommended in general for the Acaia Lunar.

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 enable/disable the beeping sound.

Zero Range Setting [ 0.rAnGE ]

1. The 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 Lunar. By pressing the tare button, any weight within ± 40 g is zeroed out by zero operation while any weight that lies 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 Lunar. Therefore, instead of tare operation, zero operation would be executed in this setting whenever tare button 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 [ Filt ]

1. The Weighing Filter Setting determines the speed at which the load receptor responds to weight and determines the weighing value. The larger the number, the more stable but slower the weighing result will be. The number shown on the LED display indicates the current filter setting.
2. Press tare button to change the parameter.

Default Unit Setting [ Unit ]

1. The Default Weighing Unit is set to grams if [ 9 ] is selected and ounce if [ o2 ] is selected.

Weighing Resolution Setting [ rESoL ]

1. The default Weighing Resolution is set to [ dEFAUL ]: the division is 0.1 g/0.002 oz.
2. Tap tare button to switch the Weighing Resolution between [ dEFAUL ] and [ hiGh ].
3.  When the Weighing Resolution is set to high, division will be 0.01 g/0.0005 oz. The default display will show [ 0.00 ] when the scale is set to grams, and [ 0.0000 ] for ounces in Weighing Mode. Note: After setting Weighing Resolution to high, the default display will show [ 0:00 0.00 ] with timer in Dual Display Mode and Auto Start Modes.

   • On: Mode enabled.
   • Off: Mode disabled.

Bluetooth Setup Setting [ bt_SEt ]

1.  Off: Bluetooth disabled. The scale does not allow any Bluetooth connection.
2.  On: Bluetooth enabled. The scale allows Bluetooth connection. The user may connect the scale with Acaia apps.

Battery Saving [ bAttSAvE ]

1. Save up to 20% of your battery by dimming the display after some time. It will return to its original brightness when the scale detects objects on it.
2. The number indicates the amount of time in seconds before the scale enters battery saving mode.
3. Tap the tare button to toggle through the options.

Pre-Infusion Time Out [ PrE_inFu ]

1. Determines when the scale times out in Auto-Start ( ) mode and two Auto-Start ( ) modes when the timer is manually started. This is most useful for long pre-infusion times and resolves the timeout that sometimes happens for slower pre-infusions.
2. The number indicates the time in seconds it will take for the scale to reset if no espresso flow or weight is detected.

Auto-Start Sensitivity [ SEnSE ]

1. Minimum weight is decreased for more sensitivity. This is ideal for slower espresso shots in the modes. Stability depends on environmental noise. The previous firmware started the timer at ~0.6 g into an espresso shot.
2. The number indicates the sensitivity of flow detection in the modes. Smaller value indicates higher sensitivity, but is recommended only for stable working environments.

Auto-Reset [ Auto_rES ]

1.  After a cup is removed, the timer will automatically reset. This setting gives you options on how long to wait for the reset. It enables the user to pull successive shots of espresso quickly in the three Auto-Start modes.
2. The number indicates the timeout value in seconds of timer reset after a cup is removed.

Reset to Default Setting [ rESEt.d ]

1. Select [ YES ] to reset all settings to default value.
2. Press and hold tare button for 1 second until [ SLEEP ] is shown on the LED to reset all settings to default.
