Tips + tricks

Maintaining your device:

  • Charge your device every month when not in use
  • Keep the lens clean of all dirt, lint, and smudges
    • Dust and debris can be removed by gently wiping the lens with a dry microfiber cloth
  • Avoid dropping or hitting your device
  • Don’t use outside of 5 – 35°C temperature range. If you bring your device in from outside, allow it to come to temperature slowly to avoid condensation.
The Nix Mini 3 and Nix Toolkit app can scan nearly any surface to get you a paint match.

Objects with textures, patterns, extreme gloss, or soft surfaces may be less accurate.

The Nix Mini 3 works best on solid opaque surfaces.

Ensure your device is placed flat to the scanned surface before scanning.
