I have a pair of T&R ultrasonic Sensors (Those that are used as range metering).

They are given to me by a friend so I do not have the specification for them.

The question is how do I measure the Capacitance and the impedance of them please?

Besides, can I remove the capacitance behavior of them by an inductor? If so, How to calculate it?

Thanks.
