Confused by a symbol and not sure what it means? This handy guide should be able to help!

The world of testing equipment is vast and filled with so many parameters and different types of terminology that sometimes it can be hard to keep track of exactly what everything means. This guide aims to help you have an easy reference point for parameters that we might mention on site and perhaps some others.
