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> or <Particle> option on the menu page: The system will directly execute
the corresponding analysis.

Roast analysis
1. Recommended Procedure
1) Use a roast analysis tray and a tray. Fill the beans into deeper side while the coffee ground into
shallower side. Note that you need to use a Scraper to make it 󲡵ush with the surface of the tray.
2) Click to power up, put the main unit over the roast analysis tray.
3) Swipe from left to right on READY page to enter the menu page. Click on the 'Roast' button
to start test. The screen will display result after complete. (See page 11 for more details)
2. Analysis Result (See Page 12 For More Details)
3. 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 0-6 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
1. Recommended Procedure
1) Use a coffee ground spoon to scoop an appropriate amount of ground coffee into the center
area of the particle analysis tray.
2) Click to power up, put the main unit over the particle analysis tray. Make sure the meganetic
ports are connected.
3) Swipe from left to right on READY page to enter the menu page. Click on the 'Particle' button
to start test. The screen will display result After the completion of the test. (See page 13
for more details)
2. Analysis Result (See Page 14 For More Details)
3. Test
1） If the amount of coffee ground taken is more than one 󲡵at spoon, the analysis of 󲡴ner
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.
3） During testing, the particle analysis tray will beep when diffusing the particle, which is a
normal phenomenon.
4. Sampling Recommendations
1）For coarse grind, please take two-thirds of a spoonful of 󲡴ne powder.
2）For 󲡴ne grind, please control it to one-third of a spoonful of 󲡴ne powder.
3）If the grind cannot be determined, please take half a spoonful of 󲡴ne powder.
4）You can adjust the sampling amount according to the actual situation to achieve better
dispersion and uniformity.

Recommended Procedure
1) Take off the protective cover.
2) Click to power up, put the main unit over the calibration plate.
3) Swipe from left to right on READY page to enter the menu page. Click on the 'Calibration'
button or start calibration by short click and then long click the button. The screen will
display 'Success' after After completion.(See page 15 for more details)
