Varia Calibre Tamper — Frequently Asked Questions (FAQ)
1. How do I change the tamping force?
Hold the base and rotate the handle. It clicks through 15, 20, 25 and 30 kg, and the selected number shows in the viewing window. Pick one setting and keep it while you dial in with grind size, so you only change one thing at a time.
2. Do I need to reset it after each tamp?
No. The mechanism resets when you release the handle, and your selected setting stays in place. Rotate the handle only when you want a different force.
3. What's the difference between an impact tamper and a regular spring tamper?
On Calibre, pressing the handle loads a spring that releases an internal impact block against the base at the setting you chose, so the force comes from the mechanism, not from how hard you lean in. The four settings let you choose that force instead of living with one fixed spring.
4. Does it fit ORBI and other 58 mm baskets?
Calibre has a 58 mm self-levelling base and is part of the Varia ORBI range, so it's made for ORBI Portable and ORBI PRO's 58 mm basket. 58 mm baskets from other brands vary slightly, and Varia hasn't published the exact base tolerance yet, so chat with us before using it with another machine.
5. Can I order it now?
Yes. It's on pre-order, so you can order it even while it shows 0 in stock, and it ships from our warehouse in Denmark. You get a 2-year warranty and 15 days to return it.
