The dilution marks are standard on all 2000 series DPD kits to get a rough idea of higher chlorine levels. Just remember that you lose a lot of precision with dilutions. The instructions for doing the dilutions are on the lid of the box at the bottom of the chlorine testing section. Also remember to use water that has NO chlorine added to it such as distilled water for your dilutions. (Well water often has chlorine added so I would be cautious if you have well water.)
