Test — and Inspection-Equipment Engineering

Test equipment and measurement systems are generally sufficiently complex to require a special engineering group to provide measurement hardware The requirement for test equipment is set by the quality-control engineer. The test — and inspection-equipment engineers, who are basically design oriented, take the quality-control engineer’s require­ments and provide the hardware that will be used by the process-control engineer in implementing […]
