I bought an ORP prob and connected it to one of the analog inputs on my WebControl. The probe was advertised to work with a Arduino. The value outputted by the WebControl is just under 200. My pool chlorine level was 6 (high). PH, CYA, etc are fine as tested at my pool supply and my test kit. I have Googled and found various levels as optimal for a pool, range from 650 to 750.
Any idea what I should be reading?
