Installing Ec/PH meter

[Leafy271]

Hello, I recently bought a refurbished Grobo and had some questions in regards to installing the ph and ec meter. I watched a video on YouTube and the video says the top slot is for the ph and my unit shows the exact opposite. Also when trying to install a green connector got loose, is this important ? Will upload pictures

I can’t help with the EC/pH as I have a Grobo 2, but I do know the green is your ground wire which you definitely want connected. Hopefully someone with a little more experience with the original Grobo can give you more help to get going.

You can put the green wire through any screw like the one right next to where your holding…should still act as a ground.

Yeah the green wire is important to reconnect. My Grobo 1 does not have those stickers on it, so I dont want to tell you the wrong thing as I know there were a few different Grobos over the years.

Grobo 3 came and only 1 probe was hooked up for some reason. I had to hookup the 2nd one myself. I think maybe they replaced one or something.
