1. Turn the calibrator ON and set the toggle switch to
CHIRP. The calibrator emits a 100ms long tone at 40kHz
(+/- 10Hz) every 500ms. The amplitude of the tone is
104dB SPL (+/- 3dB) at 10cm.
2. Enter Live Mode on the Echo Meter Touch and place the
calibrator within 20 meters to assure the signal can be
received.
3. With the calibrator chirping, you can test trigger settings
and monitoring modes.
WARNING! Do not place the Ultrasonic Calibrator near your
ears. In CHIRP mode, the calibrator emits a 40 kHz signal at over
100 dB SPL. Prolonged exposure to high intensity ultrasonic
signals may cause permanent hearing loss at audible
frequencies.
