Condenser water system, 3 inch OD pipe. I cleaned the dust and paint off of the pipe, used plenty of the grease, reviewed my menu selections, and checked and rechecked the sensor placement and distance.
I turn it on, do the zero adjustment, connect the sensors (blue upstream, red downstream) it does the "window scanning" and reports "calculation error."
I was getting "no senor detected" and then I rechecked every thing and wire wheeled to remove the paint, but the best I've see is calculation error.
Has anybody conquered this one?
