iotmumbai.bharatividyapeeth.eduwattmeter. is an instrument for measuring the electric power (or the supply rate of electrical energy) in watts of any given circuit. Electromagnetic wattmeter’s are used for measurement of utility frequency and audio frequency power; other types are required for radio frequency measurements. Learning objectives:

MFJ-969 Deluxe Versa Tuner II - RadioManual
www.radiomanual.infoThe wattmeter has an internal lamp that backlights the meter scale. The meter ON / OFF switch turns the meter lamp off and on and disables or enables the meter circuit. The lamp circuit requires power from an external 12 Vdc source, such as the optional MFJ-1312B power supply. The external supply will also supply power for the peak power detector.

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.
