Black tank:
Turn the water off, open the toilet lid, step on the flush pedal and look down the hole. There is a neck in the pipe that extends down a bit into the tank. Watch that closely and when you see the contents nearing the bottom of the neck, time to dump. Flashlight may help to see better.
Don't let it get too full or you could have a mess on your hands.
My tank sensors work much better now that I've used Happy Campers for a couple of seasons... but I still use the "look in the hole" method described by BobsYourUncle.
