 What are the modes on the Pearl model S?

The Pearl Model S scale comes with seven modes, not including Brewguide. The seven modes are as follows:

  • Mode 1 - Weighing Mode
  • Mode 2 - Dual Display Mode
  • Mode 3 - Pour Over Auto Start Mode
  • Mode 4 - Portafilter Mode
  • Mode 5 - Espresso Mode
  • Mode 6 - Flowrate Mode
  • Mode 7 - Flowrate Practice Mode

Due to popular demand, Mode 3 - Pour Over Auto Start Mode was added in a firmware update soon after the original release of the Pearl Model S. If your scale does not have this mode, it can be accessed by downloading the Acaia Updater and updating to the latest firmware.

Mode 1 - Weighing Mode

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

There are two different weighing units in Weighing Mode: gram and ounce. A green

dot will appear in the upper right of the LED display and the scale will read 0.000 when

weighing in ounces.

• The LED display shows [ 0.0 ] when the scale is measuring in grams.

• The LED display shows [ 0.000 ] when the scale is measuring in ounces.

• The readability is 0.1 g for grams and 0.005 oz for ounces.

 

Mode 2 - Dual Display Mode

In the Dual Display Mode, the scale displays [ 0:00 0.0 ] with a timer (left) and weight (right).

 

• There are two different weighing units in Dual Display Mode: gram and ounce.

• The LED display shows [0:00 0.0] when the scale is measuring in grams.

• The LED display shows [0:00 0.00] when the scale is measuring in ounces.

• 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 a maximum of

3000 grams. If the weight exceeds 3000 grams, the scale will display [ Maximum ].

 

Mode 3 - Pour Over Auto Start Mode

 

The Pour Over Auto Start Mode is designed to aid pour over coffee brewing. The scale will  detect the start of the flow from the kettle into the vessel and automatically start the timer function; the timer stops when the brewing equipment has been removed from the scale. When the vessel is removed from the scale, the display flashes the final beverage weight.

 

Display

The LED display flashes [ 0.0 ] and [ 0:00 0.0 ] when measuring in grams and the

timer is idle.

• The LED display flashes [ 0.00 ] and [ 0:00 0.00 ] when measuring in ounces and the

timer is idle.

• Once the timer has started, the LED display shows [ 0:00 0.0 ], with the time elapsed on

the left and the weight on the right in grams.

• Once the timer has started, the LED display shows [ 0:00 0.00 ], with the time elapsed on

the left and the weight on the right in ounces.

• 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 a maximum of 3000 grams.

If the weight exceeds 3000 grams, the scale will display [ Maximum ].

 

Mode Description

• If the timer has not started yet, the display will flash 0:00 and a water droplet.

• The timer will start automatically when the first flow of water is detected.

• The timer stops when the brewing equipment is removed. The scale will flash between

the beverage weight and the tare weight of the items on the scale.

 

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 next workflow.

 

Display

When measuring in grams, the display shows [ 0.0 ] before a portafilter is placed

on the scale.

• When measuring in ounces, the display shows [ 0.000 ] before a portafilter is placed

on the scale.

• The display shows [ 0.0 ] after a portafilter has been registered.

 

Mode Description

Place an empty portafilter on the scale, and the scale will register the weight of the

portafilter.

• Remove the portafilter after [ ] disappears.

 

Note

If the scale is left idle for 15 seconds or you double-tap the tare button, the Pearl Model S will automatically reset the mode to default for the next auto-tare operation

 

Mode 5 - Espresso Mode

The Espresso Mode is designed to aid espresso extraction. The scale automatically detects a cup, shot glass, or other vessel and tares the weight of the vessel. The scale will then detect the start of the flow of espresso into the vessel and automatically start the timer function; the timer stops when the flow of espresso into the vessel stops. When the vessel is removed from the scale, the display flashes between the beverage weight and vessel weight.

 

Display

The LED display shows [ 0:00 0.0 ] 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.

• 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 a maximum of 3000

grams. If the weight exceeds 3000 grams, the scale will display [ Maximum ].

 

Mode Description

• When an object (such as a cup) weighing two grams or more is placed on the scale and

the weight reading is stable, the scale will perform auto tare.

• After the scale detects the flow of espresso, the timer will start. The timer will stop when

the espresso flow stops.

• When the espresso is ready and the cup is removed, the display will flash between the

beverage weight and the vessel weight.

Note

1. In Espresso Mode, the timer will stop when the espresso flow stops.

2. The auto-tare function is performed only when the weight exceeds two grams.

3. If you leave the scale idle for ten seconds, it will reset the timer and perform tare

operation.

4. In Espresso Mode, the timer will also stop when a negative weight (i.e., removal of

a cup) is detected.

 

Mode 6 - Flowrate Mode

Designed for pour over coffee brewing. The display includes timer (left), flowrate (middle), and weight (right).

 

• The LED display shows [0:00 0.0 0.0] when the scale is measuring in grams.

• The LED display shows [0:00 0.00 0.00] when the scale is measuring in ounces

• 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 a maximum of

3000 grams. If the weight exceeds 3000 grams, the scale will display [ Maximum ].

• The flowrate is measured in grams per second (g/s) on the right-hand side of the

Display.

 

 

Mode 7 - Flowrate Practice Mode

A real-time flowrate meter mode designed for practicing your infusion stability. The current flowrate is displayed on the left, and the stability of pouring is shown through the indicator bar.

 

• The flowrate is measured in g/s and oz/s.

• Each dot on the indicator bar represents a 0.5 g/s increment. The bar provides a

visualization of flowrate stability.

 

Brewguide Mode

In any scale mode, [press and hold] for one second to enter Brewguide Mode.
