1Zpresso Grind Settings Tutorial

Greetings, fellow coffee-lover.

Do you know how to read the grind setting reference charts of the 1Zpresso manual coffee grinder? 
Here is a tutorial for y’all to learn. 

I’m personally tired of carefully adjusting the grinder when there are many clicks without knowing where I am. 

All the burrs in the grinders were calibrated by the 1Zpresso team to ensure maximum stability over time.
As the outer ring and the burr were built through precision finishing, tolerance is expected and the outer ring and the burr would touch at the first few clicks. Constant touching might damage the burr set.

Many of you know there are many models of 1Zpresso manual coffee grinder.

How to find the Zero Settings?

It is intuitive to adjust the external adjustment design as you could just note where the red dot points.

I think it is quite easy for the internal and top adjustment design as well. Adjust the adjustment dial clockwise till you feel resistance, and that’s the zero setting.

These three kinds of adjustment design share a common point of the zero setting: at the click which the crank handle is unable to move drastically.
