Dear Kurt, Richard & Crispin,

You can see and read about how I measure the power consumed in the below 
article/link:

I was disappointed in my readings, they seem about the same, loaded and 
unloaded. Maybe I should run the cement mixer (unloaded) for 18 minutes and 
measure the total kWatts/hours used.
