When using a Colorimeter (COL-BTA) on the 565 nm setting with a Go!Link (GO-LINK) or EasyLink (EZ-LINK)
interface, you may occasionally see a bad value, typically 108% T, after calibration. This value should be closer to 100% T. This problem is rare, so if you have multiple sensors and interfaces, try different combinations and you will likely find combinations that work properly.

If using the 565 nm LED is critical to your experiments, use LabQuest Mini (LQ-MINI) as your interface. An alternative is to use the Go Direct® Colorimeter (GDX-COL)
, which requires no interface.
