PLM-PH V1.02 does not work correctly

[EgaReef]

Hi,

I have a PLM-PH V1.02 that does not work correctly on P4. It works the opposite, that is, when CO2 is added in the calcium reactor, the pH value starts to rise. If the calibration, when I introduce the probe into the liquid of 4, also starts to raise the pH value.

Why?

Thanks

Hi,

Thanks for all.

New information:

This video is calibrating the probe with the pH 4 liquid

This video is calibrating the probe with the pH 9 liquid https://youtu.be/rvvAj22tREk

As you can see, the behavior of the probe is the opposite of what you should do.

Regards.
