Introduction
Whisper will detect and locate sources of ultrasonic disturbance through the use
of sophisticated circuitry.
An ultrasonic disturbance is created when objects collide. Vacuum leaks create
collisions between molecules flowing through an orifice. Pressure leaks create
collisions between molecules exiting an orifice. All gases and liquids create
disturbances if forced into, or out of, an orifice. All solid materials create
disturbances when any friction exists.
Whisper is capable of detecting and locating sources of ultrasonic disturbances
created by gases, liquids, or solids.
Whisper has different ways of indicating these disturbances. When used without
headphones, Whisper's indicators will illuminate and the unit will beep in response
to sources of ultrasonic noise. When headphones are plugged in, Whisper's
heterodyne feature is enabled, bringing ultrasonic frequencies to a range audible
to the human ear. This is often the best way to use Whisper. You can also use the
metal contact probe on solid objects. Please refer to the appropriate sections of
this manual for more information on these features and how to best use them.
