Anyone know how to test a Compool 3800 TS-5L temperature sensor?
Are they resistive, and what would nominal resistance be at 60-70F?
I'm getting an intermittent dreaded "Err1" on the Compool, and sometimes erratic temperature reports. I suspect the problem is the wiring between the controller and sensor getting wet, but before I attack it I wanted to try to isolate and test the sensor itself.
Any idea how to test such a sensor for basic functionality?
