Frequently Asked Questions
Why should I measure the "Delta" between beans and grounds?
The difference between the whole bean color and the ground coffee color indicates the "evenness" of your roast. A large delta suggests the outside is much darker than the inside, while a tight delta confirms a well-developed, uniform roast throughout the bean.
Can it be used while charging?
Yes, the CM-100plus supports operation while the battery is charging via the microUSB port, making it ideal for high-volume roasting sessions where you can't afford any downtime.
