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: Zero Tracking is measured in units of division, or “d”. 1d is equal to 0.01 grams. For example, if Zero Tracking is set to 3 d, any weight less than .03 grams will automatically be zeroed. 4. 1 d is recommended in general for the Acaia Pyxis.
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., ± 10 g for Acaia Pyxis. By pressing the Tare button, any weight within ± 10 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., ± 500 g for Acaia Pyxis. Therefore, instead of tare operation, zero operation would be executed in this setting whenever the 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 the 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 Mode Setting [ NOdE_1 ] 1. The Weighing Mode is set to On by default. · On: The Weighing Mode is enabled. · Off: The Weighing Mode is disabled.
Dual Display Mode Setting [ NOdE_2 ] 1. The Dual Display Mode is set to On by default. · On: The Dual Display Mode is enabled. · Off: The Dual Display Mode is disabled.

Auto Start Mode Setting [ NOdE_3 ] 1. The Auto Start Mode is set to On by default. · On: The Auto Start Mode is enabled. · Off: The Auto Start Mode is disabled.
Bluetooth Setup Setting [ bt_SEt ] 1. Off: Bluetooth is disabled. The scale does not allow any Bluetooth connection. 2. On: Bluetooth is enabled. The scale allows Bluetooth connection. The user may connect the scale with Acaia apps.
Battery Saving [ bAttSAvE ] 1. The Acaia Pyxis will wait for the selected number of seconds to enter Battery Saving. The LED display will dim to save power. 2. The default length of time before entering Battery Saving is 90 seconds.
Auto Start Sensitivity [ SEnSE ] 1. Minimum weight is decreased for more sensitivity. This is ideal for slower espresso shots in the droplet icon modes. Stability depends on environmental noise. 2. The number indicates the sensitivity of flow detection in the droplet icon modes. Smaller value indicates higher sensitivity, but is recommended only for stable working environments. 3. Tap the Tare button to toggle through the options.
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 before resetting. It enables the user to pull successive shots of espresso quickly in the three auto-start modes. 2. The number indicates the timeout value of timer reset after a cup is removed. 3. Tap the Tare button to toggle through the options.
Weighing Resolution Setting [ rESoL ] 1. The Weighing Resolution is set to the Default option; the division is 0.01 g for weights of 300 g or less and 0.05 g for weights between 300 g and 500 g. 2. When the Weighing Resolution is set to High, the division is 0.01 g for weights of 300 g or less and 0.02 g for weights between 300 g and 500 g.
Reset to Default Setting [ rESEt.d ] 1. Select [ YES ] to set all settings to default value.
