Using the Width Selector

Read the following instructions carefully.The example

presented may not look like the graph you just created.
Focus on the concepts and techniques presented. Specific
cases will be discussed later.

You will use the R.A.B.O.S. Measurement Template just completed
and the Width Selector to determine the correct width setting.
The Width Selector graphically depicts a single resonant peak.
The peak looks similar to a slice of a pie. See Figure 12. At the
top of the Selector is a pull tab. When you slide the tab up and
down, the width of the pie slice becomes narrower and wider,
respectively.The pointers on the sides of the button point to the
bandwidth that corresponds to the width of the slice.

Place the Width Selector over the R.A.B.O.S. Measurement
Template, positioning the center rivet of the Selector over
the response peak, as shown in Figure 13. Be sure to align
the horizontal lines of the Width Selector with those of the
R.A.B.O.S. Measurement Template.

Apply pressure to the upper and lower left corners of the Width
Selector using the thumb and forefinger of your left hand. Now
gently slide the tab up or down until the adjustable slice most
closely fits the response data. See Figure 14.
