Connect #1 to a (sine/ squarewave) generator, range 15-50kHzand #2 to an oscilloscope.
Adjust the frequency to maximum response.
A typical frequency is 27kHz.
: I have a pair of ultrasonic transducers from an old TV and I don't know the operating frequency. How can I find this out. There is no markings on the parts.
