4410A, Multipower \u00b15% Reading Accuracy RF Wattmeter with 9V Alkaline Battery<\/p>\n
4410A, RF Wattmeter<\/strong>\u00a0uses the basic principles and \u201clook and feel\u201d of the Model 43 but transforms it into a highly accurate high dynamic range instrument. The mirrored-scale linear range 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.<\/p>\n 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.<\/p>\n
