I have my new P4 and I have updated to latest firmware and connected to wifi no problems.
My question is how do I calibrate the PH probe... the manual only refers to following on screen instructions. I don't have any on screen instructions. When I go to Probes/sensor controls I the attached image.
I don't understand what I'm supposed to do and the instructions are not really helping me out.
Hello,
this is currently only possible on the device itself. Please use the keys on the device and navigate through the menu on the display to "Sensor settings->pH-value 1->Calibration".
To add to Thilo's post, make sure that the probe is activated - SENSOR ACTIVE
That is how you will get the calibration option to show on the P4 itself.
Not sure if we can link to other sites here, but this thread on R2R by Ditto explains this very well. Starting at post #20

And another one (maybe more complete) starting at post #45

Once you figure out where it's at it's very simple.
Thank you all!
