Image quality can sometimes be improved through calibration. View the images below for examples of typical quality verses necessary calibration. ![8](https://knowledgebase.cid-inc.com/hs-fs/hubfs/8.png?width=670&height=273&name=8.png) ![9](https://knowledgebase.cid-inc.com/hs-fs/hubfs/9.png?width=670&height=234&name=9.png) ![10](https://knowledgebase.cid-inc.com/hs-fs/hubfs/10.png?width=670&height=211&name=10.png) These are typical of images captured with the CI-600 and CI-602. The scan head is composed of banks of sensors for which the calibration may be slightly different, resulting in thick bands of slightly lighter or darker hue. Uneven, colorless, thin lines on image These are a result of the fibers that make up the root tubes. The imager is essentially capturing the walls of the root tube and then the soil and roots beyond. These thin lines should not be consistent from tube-to-tube if it is truly the root tube fibers. This is caused by the soil not being packed tightly around the outside of the tube. Recalibration Necessary Thin, consistently pattered stripes. These kinds of images are a result of either a failed calibration, improper connection between instrument and PC, or failed hardware. To troubleshoot, ensure you are using the proper cables and that your connections are secure. Next, try a recalibration using the provided calibration tube.
