Many variables can affect the amount of ultrasound generated by
the leakage of gas through an orifice. Such factors include the
pressure/vacuum versus the surrounding environment, how smooth
the edges of the orifice are, the diameter of the orifice, the leak
detector’s distance from the orifice and the presence of airflow,
which may dissipate the ultrasound. As you use the Marksman II,
keep in mind that these factors may affect your ability to detect
ultrasonic leaks.

output cannot be heard by the human ear. If the red indicator is on,
the unit is emitting.
