I got two ultimate sets of profilux 3.1T ex.one sets,all sensor are calibrated correctly and work properly.the difference is more than 100 between ADC1 and ADC2.
another sets,the reading of redox sensor is volatility,unstable. It can be 80 now,next second is 150, next is 100,70,130...etc,in the tank.
I calibrated it more than 10 times
I checked the difference between ADC1 and ADC2,so nearly,why?
ADC1=463,ADC2=476

profilux firmware:6.15

I will be very appreciated if you can give a reply.
