Hi, I've just done my PAT testing course and have a urgent question. I'm doing the PAT testing for my firm. In the course we kind of drifted over class 3 items as it is very rare you'll come accross them. Typically, one of the sets of scales we have at work is a class 3. I have two PAT testers, one is a Robin Smartpat 5000, and the other is a Martindale hpat 600. Neither of these have a class 3 function. What do I do about this class 3 item? Any help would be grately recieved.
