Coffee scale with four modes for coffee weight

Excellent coffee scale, I've had it for about two years and, God willing, it works perfectly. The modes are explained on the paper, and the most important mode for the scale is to place the server and the funnel, then turn on the scale, add the coffee, wait for it to beep, then pour the water—it will automatically calculate the time along with the amount of water, and its calculations are very accurate.
