The thing that both of these illustrations have in common is that var-
ious segments of the display do not "agree" with each other. This is a sure
sign that you are detecting an odd-shaped piece of iron. Notice on the rest

same information. When the ID number and the graph "agree," you can
be sure that your DeLeón is receiving a clean signal.
