ABSTRACT
This relatively unknown method has some distinct advantages compared to the other
methods discussed in chapters 10,11,13,14, and 15. The procedure is shown in Figure 12.1.
This method should only be used if there is at least a 3 in. or greater separation between the
near and far indicator measurement positions. The accuracy of this technique increases as the
distance between reading points increases. The disadvantage of this method is that there is
usually not enough shaft exposed to be able to spread the indicators far enough apart to merit
using the method except for very special circumstances.
