Hello Thank you for the goods, all the values ​​work. But the Ph measurement does not work at all. I put new batteries in 2 times, but when measuring the Ph of water or pool water it does not show anything. Only the temperature. Can I somehow reset the device or repair it? I mainly need the Ph. I am also sending a video, thank you for your help. http://www.onicom.sk/zmaz/ph.mov
