PURPOSE:To improve the reading accuracy of a measured value by altering to 0.7314 the wavelength contraction rate of a meter detecting the ratio in velocity between a forward power and a reflected power to prolong the distance between input and output contacts of a transmitter, and thereby improving the reproducibility of reset at the time of detection. CONSTITUTION:On the occasion when a detector is connected to a transmitter for general use to detect the ratio in velocity between forward and reflected powers oscillated therefrom, the wavelength contraction rate of the dilector, serving as the operational coefficient thereof, is altered from 0.66 to 0.7314 to prolong the distance between input and output contacts of the transmitter, and an amplifier is interposed in the circuit of the detector to improve the reading accuracy thereof. With respect to the improvement of the wavelength contraction rate of 0.66, in particular, the mechanical length between the input and output contacts of the transmitter is adjusted to be lambda/2, and based on a counted value thus obtained, the numerical value of 0.7314 is calculated. |
