I did a water test and the Salt and TDS readings were exactly the same and basically zero in the salt percentage. When I added salt to the water I got a salt reading higher than the TDS as well as a percentage. So I have to assume that I have to subtract the TDS value to get the actual salt value, which is not explained in the instructions. I will get a test solution to test it further. If it is NOT correct, it will be returned
