Scale Overview

LED Indicators

Flow-Rate Indicator

The Flow-Rate Indicator is an LED bar on the top of the display. It helps you visualize your espresso flow rate in real-time and helps you spot channeling during brewing. The indicator measures flow rates with lit LEDs starting from 0.1 g per second on the left to 3.4 g per second on the right. When the flow rate exceeds 5.0 g per second, the last three LEDs will light up with enhanced brightness, indicating a high flow rate. During an espresso brew, the Flow- Rate Indicator will display the highest peak flow rate of this brew with a single bright LED.
The Flow-Rate Indicator can be activated in all modes. You can turn the indicator on or off in the advanced settings menu.

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.

Battery Charging

You can use the included USB Type-C charger cable to connect the Lunar 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 Lunar 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. The battery charging function will be enabled again when the scale has cooled.

Advanced Settings

You can also tailor the scale according to your preferences by changing the system settings, such as adjusting the screen brightness and turning the Flow- Rate Indicator on or off. There are also customizable espresso workflow parameters such as the adjustable pre-infusion time out and auto-start sensitivity settings.
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.

Brewing Modes at a Glance

Mode 1 – Weighing Mode
The weighing mode for all weighing purposes. Enter [Advanced Settings menu] to select gram or ounce as your weighing unit.

Mode 2 – Dual Display Mode
With a 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 – Timer Starts with Flow Mode ( )
When the scale detects the flow of espresso, the timer starts. The timer will stop when the flow stops.
*Please note: The flow detection mode is designed to detect the slow trickle of a shot of espresso. The timer may not trigger when attempting to pour from a kettle.

Mode 4 – Auto-Tare Timer Starts with Flow Mode ( )
This mode is designed for baristas who would like to measure the time of the shot starting from the first few drops of espresso. When a stable weight is detected, the scale will perform the auto-tare operation. After the scale detects the espresso flow, the timer starts. The timer will stop when the espresso flow stops.

Mode 5 – Auto-Tare Auto-Start Timer Mode ( )
This mode is for baristas to measure the total time of a shot including the pre-infusion time. After a stable weight such as a cup is placed on the weighing pan, the scale performs auto-tare and starts the timer.

Mode 6 – Auto-Tare Mode ( )
In this mode, the scale will only perform auto-tare without automatically starting the timer. Put the cup on the scale and auto-tare will be performed. Pull the shot of espresso as usual. When the cup is removed from the scale, the display flashes the final beverage weight and also shows the tare weight of the cup.

Calibrating Your Scale

The Acaia Lunar is a precision instrument, and regular calibration is recommended with frequent use. To perform a smart calibration, select Weighing Mode, switch the unit to grams, and follow the steps below:
