RONALD Yesi understand. You need to buy a small bottle distilled water. After one test. Clean the tester with the distilled water, then dry it with hair dryer. Or you can use paper tissues. I distilled water it will show no reading. This is the biggest proof that this instrument works well. I have tested it in various types of water. It gives accurate reading when the water is completely calm. So put in water and let it settle.
