Orp expantion not working
How would it test if the orp expansion is working. It use to work fine. Then just stopped working. I get 0 reading from the orp. Even if I try calibrate it and use the terminator. Im using the ra+ no other add ons.

Is the led on the side turned on?
Try another 12vdc power supply

Re: Orp expantion not working
yup green led is showing, I have tested another 12v dc and another orp probe both with no luck. Is there any way to determine if the orp unit itself is giving out any outputs?

I will try test the unit on a friends ra. If no luck we can look at analysis I think
