Resolution of an error on Orpheo 2: Practical guide and troubleshooting steps

Client :
Good evening, I have an error message on my orpheo 2, "ERR ORP+PH". I have checked the installation, recalibrated 3 times, in reg no error message, and in on it runs for 30 seconds and then error message.

Client :
Cool these tips, but I calibrate them in ph7-9 solutions and the other 650mv, they react immediately and I have the correct values, that's what I don't understand. Is there a way to reset this device? Reset.

Agent :
Unplug/replug in general. Do the tests, it's the simplest way.

Client :
I'm at work in the evening but tomorrow morning I will do the previous tests with salt and vinegar. Thank you, 😉

Agent :
Good luck.
