The method is for preparing data read from data communication network for testing purposes. Current sensor 12 in series with the input line senses inductive load current. The system is dynamic so that each time a lockable storage enclosure is used, one or more new identifying characteristics are associated with the lockable storage enclosure for locking and unlocking the lockable storage enclosure. A point where electric field concentration on the surface of the lightning receptor is greatest is moved from the boundary to the tip of the lightning receiving protrusion, so as to significantly reduce a possibility of blade damage associated with lightning striking the boundary when being stroke by the lightning. It has a pipette tip ejection mechanism with a sinusoidal stripper bar. Accordingly, in certain embodiments, the sleeve is a protective silicone sleeve that is adapted to hold andor contain a container, thereby protecting the container from damage.
