Place the cursor at the noise floor, close to the 40 kHz peak and click once with the mouse. Then move the cursor to the top of the 40 kHz peak and read the difference at the bottom of the Power Spectrum window (the ”Distance”...
  • Page 7 When the T10 is set to this test mode, the output level is much lower than the 40 kHz mode and it is possible to put the microphone in direct contact with the front of the T10 (actually, the M500, M500-384 and the external D500X microphone can all be inserted into the center hole of the openings for the speaker, if the microphone horn is first removed).

    Mode 3, External sound source The T10 can also be used as an ultrasound speaker with built-in amplifier. That way, it can play any type of sounds, not just the test signals. Using the T10 in this mode requires some knowledge in using/connecting audio devices, so it is recommended for experienced users only.
