That and a decent voltmeter along with a sweep tone generator can be
used to draw a graph of impedance against frequency, though to be
accurate, you need to use an oscilloscope and a couple of low value
resistors in the circuit to detect any frequency dependent phase shifts
in the load, or use a hall effect sensor to generate a voltage to drive
the X plates on the 'scope. If you have a DAW, then you have a way to
generate a sine or pink tone good enough for the job, even using a free
DAW program such as Audacity.
Sorry, finger trouble, The X plates are drive by the voltage, and the Y
plates by a voltage derived from the current, in the same way as the
stereo imaging displays are by the left and right channels.
