WAVE-LEAKAGE MEASURING APPARATUS AND MEASURING METHOD

摘要

A wave-leakage measuring apparatus compares the power density of leakage waves in portions on the upper side, the lower side, the left side, the right side of highfrequency heating apparatus by two steps. The locations of maximum leakage are selected by a central data processing computer, which serves to bring one of the power-density detectors to a maximum wave-leakage location by the robot, whereby to precisely measure the power density of the leakage waves while the wave-mode converting apparatus makes at least one rotation to automatically decide the quality of the product.
