A pelvic extension frame for removable attachment to the waist. This system combines results from an inspection tool and design layout data from a design data repository corresponding to each mask layer being inspected with a computer program and a predetermined rule set to determine when a defect on a given mask layer has occurred. Components including a main circuit contact, a contact switching mechanism, an operation handle, an overcurrent tripping device, an earth leakage detection circuit combined with a zero-phase current transformer, and an earth leakage tripping device, are retained in the main body housing. A register circuit, including an input shift register and a plurality of storage devices, receives the data signal and the control signals, programs the storage devices as directed, and generates a plurality of trim control signals based on the states of the storage devices.
