Abstract

PURPOSE:To examine the characteristics of the photosemiconductor in a high efficiency by a method wherein the mounting of a semiconductor element on a base is detected, a driving pulse current gradually increasing is passed through the element and a light emission output based on the continuity of currents is detected. CONSTITUTION:A pellet 1 attracted to a vacuum chack by a control drive of a pulse motor is position-fitted by a movement of an arm means 11 and then, placed on the base 2. A pulse current generator 16 is energized by a pressing force of the pellet 1 produced at the time and the pulse current gradually increasing is supplied to the pellet 1. Since the pellet 1 makes a light emitting action responding to said driving current, the light emitting action is detected and corresponded to the above- mentioned driving pulse current level to be sweep-displayed on a motor 18. With such a manner, the current and the light characteristic of the pellet can be displayed and the quality of the pellet can be judged simply and automatically.
