Testing Inductors
Inductors, like capacitors, produce an elliptical signature on the Tracker 2000. Figure 5-35 shows
you the signatures produced in each of the 12 range and frequency combinations by a 250mH inductor.
Figure 5-35.—Signatures of a 250mH inductor.
Ferrite inductors can also be checked using this unit; however, the signature produced will be
different. Ferrite inductors operate well at high frequencies, but saturate at low frequencies. Figure 5-36
shows the signature of a 490mH ferrite inductor tested at 60 Hz. In low and medium 1, you can see that
