    • RE: Calibration error

      @Will-Dickson If I still want to order a second colorimeter, should I just put in that order separately?

    • RE: Calibration error

      @Will-Dickson I was also thinking about ordering a second colorimeter kit to make it easier to use the two different LED boards without having to take it apart every time. So perhaps I could just order a full kit and swap out different parts to help diagnose the issue?

    • RE: Calibration error

      @Will-Dickson I have not experienced any issues connecting the Arduino, and the Samples box is set to 500. So as you say, it seems the problem could be with the sensor. However, I still do not reliably see the LEDs flash when I try to calibrate so could that indicate a different problem?

    • RE: Calibration error

      @Will-Dickson I just tried this with both boards and am still getting the error. So maybe the sensor itself is not working properly?

    • RE: Calibration error

      @Will-Dickson Actually I am seeing the LEDs flash irregularly - for a while I was seeing just the red flash when I clicked calibrate, and then when I clicked "ok" on the error message the blue would flash. After disconnecting and reconnecting, I am seeing nothing when I click calibrate and still the blue flash when I dismiss the error message. The wires are connecting the correct pins but I'll try reconnecting them so they are not twisted.

    • RE: Calibration error

      @Will-Dickson I have gotten it to work with board B but am still getting the RSP_ERROR: [0, calibration failed] error when I try calibrating with the standard RGB board, both with water and empty.

    • Calibration error

      I am unable to calibrate my colorimeter. When I try to calibrate with a cuvette of water, I get the following error: RSP_ERROR: [0, calibration failed]

      When I try calibrating with the colorimeter empty and the slider open, I do not see the LEDs flash and I get this error: response from device is too short.

      Any troubleshooting ideas? Is it possible I assembled something incorrectly?

    • RE: Clibration problem

      @Will-Dickson I am having the same problem mentioned here and I get the same error and do not see LEDs flash when I try to calibrate with the slider open.
