Wearing the appropriate electrical safety equipment is a necessity that doesn't always epitomize "easy". Donning safety goggles, face masks and rubber gloves can make performing tasks and motor testing difficult. Or, for an "easy" alternative, view PdMA Corporation’s video on safety at http://www.pdma.com/webinars/PPE/PPE.html.
Also, don't forget to always second-check your connections, software selections and probe settings to ensure accuracy and efficiency.
