Orp reading zero
Orp reading zero
I purchased and Orp and Salinity probes sometime ago and today I decide to install them. The salinity probe is working just fine but the Orp probe is reading 0. I have tried different expansion port channels and even different cables but the probe still reads 0. I have not tried to calibrate it yet I was just trying to get it functioning. The probe itself was still stored in its shipping fluid and was unused until today. Any help would be great

I ran the i2cscanner.ino I found here and below are the results

Also I am now seeing the salinity probe starting to drift

Re: Orp reading zero
The module is there.
4C = ORP
When you enter calibration, does it show zero?

Re: Orp reading zero
I tried to calibrate even thou I didn't have the calibration standard and got no reading on the zero point and the 470 point.

I am having the same problem.
Any Advice ?
