To provide an inspection system for equipment storing inspection data of equipment in an equipment main body in a standard format for a long time period.

The system is composed of equipment having at least one of an AD converter converting a voltage value to be input to an input terminal into a digital value, and a DA converter converting an inner computing value into a voltage value to apply the converted voltage value to an output terminal; a PC for inspection connected to be communicable with the equipment; at least one of a voltage generation device applying a voltage value for inspection to the input terminal, and a voltage measurement device measuring a voltage value at the output terminal; and an inspection data storage unit built in the equipment. The PC for inspection includes at least one of an input inspection means obtaining data in which the voltage value to be instructed to the generation device is converted into the digital value by the AD converter to store the data in the storage unit, and an output inspection means obtaining measurement data of the voltage to be generated at the output terminal by issuing an instruction to the DA converter to store the inspection data in the storage unit.
