Received a relatively large indoor coverage system for a hospital this morning and while I was setting up my test rig I must have overlooked something, all of my test results were way below what they would typically be, so I ended up spending over an hour troubleshooting my own gear trying to find the culprit. Temporarily gave up and decided to go give my head a break, went for lunch, had some coffee, came back, found the problem in 5 minutes, ****. It's amazing what a full stomach and some caffeine can do for productivity.
