Abstract
PURPOSE: To improve the reliability of a measurement by making plural contact pins contact with a wired substrate automatically and by testing whether an element of the desired value is present at the desired position by means of an automatic microprogram processing.
CONSTITUTION: The automatic testing device consists of the arithmetic processing part A, test signal part B, changeover part C and unit bed D. The arithmetic processing part A controls the device in accordance with a program. The test signal part B sends both a read value and a decided data to the arithmetic processing part. The changeover part C selects an optimum reference resistance for an element to be measured in the substrate to be measured. The unit bed D supports a unit to be measured.
