Function operation

Test

There are three methods to start the test

1. Click the button: In smart test mode, the system will automatically determine whether to perform roast analysis or particle analysis.
2. Tap the screen on the Home Page: In smart test mode, the system will automatically determine whether to perform roast analysis or particle analysis.
3. Click the <Roast Analysis> or <Particle Analysis> option on the menu page: The system will directly execute the corresponding analysis.

Roast Analysis

Recommended Procedure

1. It’s recommended to use the deeper side of Coffee Beans while the Coffee Grounds can use either side of it.
2. Evenly spread the coffee beans or ground coffee on the Roast Analysis Tray and use the Scraper to make them level with the brim of the tray.
3. Place the Main Unit over the tray and start the test.
4. Wait for the test to be completed.

Cautions

1. Light Source: Roast analysis utilizes near-infrared light sources (850nm, 940nm) for testing and analysis. White light is used for auxiliary functions such as smart tests and silver skin detection.
2. Silver Skin Detection: You can choose whether to enable the silver skin detection function for coffee beans or coffee grounds in the settings. You can also adjust the sensitivity of it.

Particle Analysis
Recommended Procedure

1. Take an appropriate amount of coffee powder with a small spoon (refer to sampling recommendations) and place they are located in the central area of the particle analysis tray.
2. Connect the main unit to the particle analysis tray, making sure that the magnetic connection between the tray and the main unit is properly connected.
3. Start the test.
4. Wait for the test to be completed.

1. If the amount of coffee ground taken is more than one flat spoon, the analysis of finer particles may be affected.
2. After the Smart Diffusor function is turned on, it can automatically conduct diffusion according to the current particle distribution. If the particles have already been evenly distributed, the diffusion will not be carried out again.

Sampling Recommendations

1. For a coarse grind, please take two-thirds of a spoonful of fine powder.
2. For a fine grind, please control it to one-third of a spoonful of fine powder.
3. If the grind cannot be determined, please take half a spoonful of fine powder.
4. You can adjust the sampling amount according to the actual situation to achieve better dispersion and uniformity.

Roast Degree Calibration

Instructions

1. Remove the cover on the Roast Degree Calibration Plate first ( Be aware not to scratch the calibration area ).
2. Place the calibration plate under the Main Unit and make sure the handle is facing the direction of the button.
3. Enter Calibration Mode and tap <Start> to start the calibration.
4. You can exit calibration mode after calibration success.

Settings

On the menu screen, click the <Settings> option to enter the settings page.

1. Roast: The settings related to roast analysis.
2. Particle: The settings related to particle analysis.
3. General: Device settings like language and screen brightness.
4. Device Info: See more Omni product information.
5. Factory Reset: Long-press on the reset icon and wait for the progress bar to complete filling (5 seconds). This will restore the device to its factory settings (Please note: This operation will clear all the history records, reset all settings and reboot the device).
