  1. Remove the battery from the spectrometer.
    Note: If you are collecting data via USB, you do not<\/strong> need the battery installed or the AC power cable connected. Removing both often solves most issues.<\/li>\n
  2. Reboot your computer or Chromebook.<\/li>\n
  3. Unplug and replug the USB cable.<\/li>\n
  4. Try a different USB cable \u2014 use one you know works.<\/li>\n
  5. Use a shorter USB cable if one is available.
    Shorter cables are more reliable for data communication.<\/em><\/li>\n
  6. Avoid using any USB adapters.
    Do not use USB standard-to-USB-C adapters or any converters; use a direct USB cable connection.<\/em><\/li>\n
  7. Use a powered USB hub between the spectrometer and your device, if possible.
    This can help ensure consistent power and data transfer.<\/em><\/li>\n
  8. If you are using the Spectral Analysis Progressive Web App (spectralanalysis.app) in Chrome, make sure you have connected properly. See How do I connect USB sensors to the Progressive Web App version of Graphical Analysis (and other Vernier apps)?<\/a><\/li>\n
