testing self made ro parameters

Hi, I decided to make my own RO water and bought the Aqua Mecic Easyline 300. The product works great and I made 25 liters yesterday. Now i want to make sure the RO water has the correct parameters. Is it correct that i need the test the following ? 1) TDS: 0 2) PH: 7 3) ALK, CAL, MG: 0 4) NO3...
