Zerno Z1: espresso grind setting
Start a little coarser than where the burrs touch, and dial in from there. Finer is toward 0 µm (knob clockwise).
Where to start
- Usual espresso range: 50 to 250 (µm on the dial).
- One small step: 10 µm on the dial.
- Zero point: Before the first power-on, set the dial above 200 µm: Zerno says the zero may shift in transit. To re-zero: with the grinder running, turn toward 0 until the burrs just touch, switch off, then reset the dial to 0 (manual, section 2.1).
- The dial reads the burr gap in microns. Never turn it more than 1400 µm coarse: the dial can unscrew.
