How to read the dial

Zero: 0 = burrs just begin to touch (factory zeroed; user re-zeroing procedure in manual)
Two burr sets swap in 1-2 minutes without re-zeroing, per Niche

Niche grind size guide
Good to know
- No published or community microns-per-mark figure found, so microns_per_step and zero_offset_um are null. Use the Niche chart.
- Niche's chart does not say which burr set it is for. The espresso range (0-10) only works with the espresso burrs; the manual says the filter set cannot grind fine enough for espresso.
- French press is '45+' on Niche's chart; left out because the top of the printed scale is not confirmed.
- Manual: a quarter turn of the hopper is about 30-40 marks, so one rotation is roughly 120-160 marks. Not an exact figure.
- Hopper holds 60-70 g (manual). Motor rating 130 W on the 220-240 V model; RPM not published.
- Run the motor briefly every 10 marks when moving finer (manual). Do not run at 0.
