Abstract: A system is disclosed for storing, organizing and protecting from shock movable electronic equipment, and cables used to electronically test runout on a turbine's rotor. Each piece of electronic equipment used in the electronic runout measurement is stored in a designated area in a mobile toolbox within an insert. The inserts serve to secure the equipment from excessive movement and shock when the toolbox is moved. Preferably, the inserts are custom foam cutouts, which are machined to fit the electronic tools and computer comprising the electronic equipment used for the electronic runout measurements. The thickness of the foam is adjusted according to the particular drawer in the toolbox in which the foam is inserted for purposes of storing the electronic equipment.
