2. Operating Instructions

The COFFMETER A1 offers precise analysis for both whole beans and coffee grounds.

2.1 Measuring Roast Degree (Whole Beans)

1. Select the deep side of the dual-sided sample tray.
2. Fill the tray with a single layer of whole coffee beans.
3. Place the COFFMETER A1 analyzer directly on top of the filled tray.
4. Power on the device and select the 'Roast' function from the menu.
5. Press 'Test' to initiate the measurement. Results will be displayed in approximately 3 seconds, showing the Agtron value and roast level.

2.2 Measuring Roast Degree (Coffee Grounds)

1. Select the shallow side of the dual-sided sample tray.
2. Fill the tray with a thin, even layer of coffee grounds.
3. Place the COFFMETER A1 analyzer directly on top of the filled tray.
4. Power on the device and select the 'Roast' function from the menu.
5. Press 'Test' to initiate the measurement. Results will be displayed in approximately 3 seconds, showing the Agtron value and roast level.

2.3 Particle Size Analysis (Coffee Grounds)

The device can also analyze the particle size distribution of coffee grounds.

1. Place a small amount of coffee grounds onto the designated vibration plate.
2. Place the COFFMETER A1 analyzer on top of the plate.
3. Power on the device and select the 'Particle' function from the menu.
4. Press 'Test'. The device will vibrate to distribute the grounds evenly and then display the particle size distribution, including ratios and counts for different coarseness levels.
