Lighttells Coffee Roast Color Analyser

Using the CM-100 is simple

1. Fill the tray with whole beans or ground coffee.

2. Using the metal ruler, ensure the coffee is evenly spread and as level as possible.

3. Once the CM-100 has warmed up, select your application (ground or whole bean) and place CM-100 over the coffee.

4. Then press enter. You can rotate the device at 90 degrees to check the average of measurements.
   

Troubleshooting

The CM-100 measures the roast by both color and the distance between the light sensor and the surface of the beans. If you are experiencing inconsistent readings on the CM-100 even after calibration, ensure that the beans are spread evenly in the dish. The beans must be at a consistent height and width within the dish and must not exceed the height of the dish. We suggest using a ruler (as shown above) to evenly spread whole beans and ground beans to achieve a correct reading.
