What to do if Hettich MIKRO 220 displays N > ROTOR MAX after changing the rotor?
- RRebekah FrederickSep 13, 2025
If your Hettich Laboratory Equipment shows 'N > ROTOR MAX' after changing the rotor, it means the new rotor has a higher maximum speed than the previous one and hasn't been detected yet. Set a speed up to the maximum speed of the previously used rotor. Press the [START/IMPULS] button to perform rotor detection.
