General Information
Whisper is sensitive only to ultrasound (40 to 43 kHz) and is unaffected by audible
noise.
INTERNAL NOISE CONTROL (I.N.C.) allows the use of this instrument in
extremely noisy environments such as mechanical rooms, around operational
chillers, etc. Drag your finger upward on the sensitivity touch pad to increase
sensitivity when experiencing little or no environmental noise. Drag your finger
downward on the sensitivity touch pad to reduce sensitivity in response to an
increase in environmental noise.
Many variables can affect the amount of ultrasound generated by the leakage of
gas through an orifice. Such factors include the pressure/vacuum relative to the
surrounding environment, how smooth the edges of the orifice are, the diameter of
the orifice, Whisper’s distance from the orifice, and the presence of airflow, which
may dissipate the ultrasound.
As you use Whisper, keep in mind that these factors may affect your ability to
detect ultrasonic leaks.
