HES has designed and manufactured automatic test equipment (ATE) either as stand alone machines or as part of much larger machines.  The machines can be manually or automatically loaded to suit the product and the quantities produced.  Often, when only small throughputs are required a semi-auto test/inspection rig is produced allowing an operator to, say, press fit components together and test the assembly for operation before allowing it to be removed.

 As far as possible poka-yoke principles (mistake proofing) are used when designing the equipment.   A poka-yoke device is one that prevents incorrect parts from being made or assembled, or easily identifies a flaw or error.
