I recently picked up a Beseler PM3L color analyzer and am at somewhat of a loss as to how to use it. I'm familiar with the basic concept of what it does but not the specifics of its operation. Does anyone have a manual, or a link to a manual, or any other resources that might help me? Information about these things seems to be almost nonexistent on the internet. I'm really excited to get into RA4 work and am nearly set up to do so. I want to start using this analyzer from the beginning to better understand what's happening with my exposure.
