Years ago, I had a Physio Control NIBP Monitor to fix. The reported fault was "It makes all the right sounds, but the cuff doesn't blow up". Turned out that the hose to the cuff was plugged AROUND the rear panel earth stud. My supervisor nearly wet himself when he saw what they'd done, and the senior Medical Physicist took a picture of it. Since then, the latter regularly takes pictures of howlers like this"
