"If the job is worth doing, You'd think I would not have to write a section like this, especially as most kit comes with at least some form of manual showing the user how to use their brand new purchase. Well, you'd be surprised how many bits of kit are purchased by the buying department and, by the time the kit gets to the poor chap who's got to install it, the manual and other good things have been removed for "safekeeping"! So, the next line of defence is to get in the salesman who sold the kit to the concern in the first place. But, and this is a huge but, the salesman may only have the basics under his belt and will usually teach the new user nothing more than a bunch of bad habits. In this game I have pretty much seen anything and everything with regards instruments and their use! So it kind of proves this is probably the most important section in this chapter on Measurement Techniques because if the measuring equipment is not connected up correctly, how on earth is one meant to get sensible readings! Two factors determine how the equipment is connected. The first is the actual feed type (single, split, 3-phase, etc.), the second being the type of complaint. The first part is somewhat self explanatory, but it's the second that often leads to issues not being considered. We start with the basic problem - a lack of common sense...
