If the SKOPE electronic controller has a suspected fault, care must
be taken to ensure accurate diagnosis. The controller has various
programmable parameters that effect operation such as time delay

Confirm all wiring and terminations are correct. Check probe resist-
ance is correct, and replace any faulty components.
