Abstract

PURPOSE: To perform connection checking of pin connectors and pins for each pin readily and quickly by comparing the output voltage of a test pulse generator and the voltage of a voltage supervising part when the output of the generator is connected to the IC being tested.
CONSTITUTION: This system is provided with a test pulse generator PG and a multilicity of pin connectors C into which the connection pins CP of the IC being tested are inserted and a switch SW which selectively connects the output of the PG to any one of the connectors C. A voltage supervising part VM is provided via resistor to the output of the PG. The connection of the pins CP selectively connected to the PG by the SW is checked by comparing the DC voltage having been set in the output of the PG and the voltage in the VM.
