Bird 4410A & 4410-3,5,6,7 & case wattmeter package
The Model 4410A uses the basic principles and "look and feel" of the Model 43 but transforms it into a highly accurate high dynamic range instrument. The meter has 2 switchable ranges, 0-1 and 0-3. Power is read as a multiple of the value indicated by the pointer, the decimal point location depending upon the range switch position and the factor printed on the plug-in element. Power ranges covered by individual elements are 2 mW to 10 W, 20 mW to 100 W, 200 mW to 1 KW and 2 W to 10 KW, full scale. For most elements, accuracy is 5% anywhere above 20% of full scale. The circuitry operates from a standard 9V alkaline battery.
