Hello,
I have just tried to calibrate my Redox probe (PIIIex and probe are new).
and it gives the following results :
whether the probe is unplugged the value ADC read is 531mV
and when I plug the probe (unplugging all the other probes/control cables) the value is almost the same (oscillating between 530 and 534mV).
Of course with such a calibration, the value for redox potential read on the PIII is always -999mV.
Is this something you have already seen ?
Do you think I could plug the PH probe in the Redox socket to identify is the PIII is faulty or (if the value changes from the eternal -999mV) if the probe is faulty ?
Many thanks
