This is a good time to:
- Run your spectros through any diagnostic programs that are available for your devices. Barbieri has a software tool called "Service Report" for all of their instruments and X-Rite has a utility called "i1Diagnostics" that has been recently updated to work with the i1Pro 2 and IO 2 table.
- An even better way to have assurance of instrument accuracy is to measure a control tool on a regular basis. This control tool would be a control strip that is specially made to be stable and colorfast for a long time. We sell the Vogelsong COLORef and also bundle it with our MeasureWatch service of Maxwell. This combination gives you a quality control strip as well as an easy way to track the accuracy of your device as you make routine instrument checks over time. The idea is that if an instrument is going out of spec. you'll know about it ahead of time.
