I'm interested in monitoring the run time of my furnace. I can easily bring in a signal which goes on and off with the furnace. I'd like to have a way of accumulating the run time of the furnace.
I could set up an Oscillator, And its output with an oscillator, and run the output to an Event Counter. The count output of the Event Counter could represent the accumulated on time. This seems a bit crude. Is there a better way?
