  • Page 33 The measuring device and load resistances in the QA-ES are isolated from the processor unit and the housing by a galvanic shield. This protects the user if a fault in the QA-ES produces ground currents during the measurements. This interface is based upon opto-couplers and various mains transformers for the user interface and the measuring device in the QA-ES.
