Webwattmeter charges the battery and operates from an external power supply. When ac power is removed, the wattmeter operates from the battery. Theory Of Operation On any uniform RF line section there are voltages, currents and standing waves present when RF power is applied. These are the results of two travel-ling waves, forward and reflected.
