Watts, Vars and VA
wattmeter which can measure real power; a modern equivalent would be the Fluke model 41 power meter. The Fluke meter can only achieve an accuracy of a few percent because of its use of a clamp-on current probe. Accuracy of less than 1 percent will require avoiding the clamp-on probe for measuring the current.
