"The 6154 is a wattmeter from Bird. A Wattmeter is an instrument for measuring the electric power (or the supply rate of electrical energy) in watts of any given circuit. Electromagnetic wattmeters are used for measurement of utility frequency and audio frequency power; other types are required for radio frequency measurements.","Additional Features:","The Bird 6154 Termaline RF Wattmeter that is designed to measure RF power under non-radiating conditions. The wattmeter is built around an accurate 50 ohm coaxial load resistor which becomes the transmitter load element, providing a practically reflectionless line termination from 25 to 1000 MHz. Power input to the load resistor is measured by a four-range crystal voltmeter reading directly in watts (5\/15\/50\/150 W). A toggle switch determines the scale."
