****** Page 17 ****** Auto Sleep Settings Auto Sleep Settings can also be configured in the Acaia App. 1. 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 weighing pan must be less than 50% of capacity, i.e., less than 1 kg 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 weighing pan is cleared. 2. When Auto Zero setting is on or enabled, the scale displays the initial weight directly regardless whether the weight is over 50% of capacity. Zero Tracking Zero Tracking is a function for maintaining the zero indication within certain limits automatically. 1. OFF: It is not recommended to turn off the Zero Tracking because the zero indication would draft easily as room temperature changes. 2. 0.5d—3d: For example, since each division is 0.1g, 3d = 0.3g. When Zero Tracking is set to be 3d, any initial weight between +1- 0.3g on the weighing pan would be zeroed out. 3. 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 T button 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 T button, any weight within +1- 40g is zeroed out by zero operation while any weight lays 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 T button is pressed. Chapter 5: Configuration
****** Page 18 ****** 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 weighing result. However, zero operation does not increase the scale capacity. Weighing filter setting 1. The number shown on LCD display indicates the current filter parameter which determines the speed for load receptor to response 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 1. The Default Weighing Unit is set to be gram. Weighing resolution 1. The default Weighing Resolution is set to [ dEFB/-/k l: the division is O. lg under weight of 1000g and 0.5g from 1000g to 2000g. 2. When the Weighing Resolution is set to high, division will be 0. lg throughout the entire time from Og to 2000g. Bluetooth Password Bluetooth On/Off Chapter 5: Configuration 18
