Testing the Microphone Element

Use the available Ultrasonic Calibrator to test the microphone
element on the Echo Meter Touch. Since ultrasound is beyond
the range of human hearing, verifying performance requires
special equipment. The Ultrasonic Calibrator helps you test both
the microphone and the full recording system.
The calibrator uses a 9V alkaline battery (included with the
calibrator). When the battery is depleted, the calibrator can no
longer provide a tone and its LED no longer illuminates. While
the recorder may still emit sound at this point, it cannot be used
as an accurate calibrator until the battery is replaced.
The calibrator offers two modes of operation. Calibration mode is
used to test the microphone at close range and Chirp mode is
used to test the entire system at a greater distance.

4.1

Calibration Mode Microphone Testing

1.

Remove the clear calibrator
microphone adapter by sliding it
off the calibrator from the
bottom.

2.

Turn the calibrator ON and set
the toggle switch to CAL
(calibration). The calibrator
generates a 40 kHz inaudible
tone.

3.

If you are using the Pro version of the EMT 2, set the gain
to Medium in the Advanced Settings of the app.

4.

Enter Live Mode on the Echo Meter Touch. Make sure
you are in expanded view or the spectrogram will adapt
to the calibration tone and stop scrolling. Also turn the
