INTRODUCTION TO QUALITATIVE MEASUREMENTS
As a technician, you are responsible for repairing and maintaining complex electronic systems. The basic
ability to repair a specific piece of equipment is only the first step in becoming a qualified technician. Your
ultimate goal should be to become proficient at systems fault isolation — in other words, to know the entire
