Color Sensor Calibration

I have an RVR that seems to have a miscalibrated sensor. It will not read or barely read the color cards on the floor. If I move the cards just a few cms closer, it detects it.

It is a well lit area and it is a fully charged battery., The sensor is lighting up and there is no debris or scratches on the sensor cover.

I tried the same cards in the same position with two different RVRs and had no issues with it detecting the colors.

Is there a calibration update or procedure we can do?

Did you check the color graph between each unit. Maybe one of the colors is not being detected correctly.

I did. The one unit that is not working the colors are barely detected when the color cards on the floor. The same cards in the same spot with two different RVRs, the colors are detected just fine.
