Having a problem with a FMC K machine(21548 hrs). When I go into calib. mode and try to calib. condo cells I get the message "Conductivity Offset Error". I tried swapping another sensor board and still get the same message. Has anyone seen this before?

I'm not sure I'm remembering this right, but I think you have to trick the machine by putting a good value ie: 13.5 then hit confirm and go back and do the condo cal again.

It is your function board!

Try deleting the calibration first. (I forget how but someone can post it) This works 25% of the time.
