Orp expantion not working

butcherman · Post by **butcherman** » Tue Jan 14, 2014 5:02 am

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

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?

You may need to send it back for analysis.
PM for RMA.

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