STETHOSCOPE (CONTACT) MODULE.
This is the module with the metal rod.
This rod is utilized as a "waveguide" in that it is sensitive to ultrasound that is
generated internally such as within a pipe, bearing housing or steam trap. Once
stimulated by ultrasound, it transfers the signal to a piezoelectric transducer located
in the module housing directly behind the “wave guide”. For placement align the
plug with the corresponding receptacle in the front end of the pistol housing and
plug in.
PISTOL-GRIP HOUSING
DISPLAY PANEL.
In the Operation Mode, the Display Panel will show intensity levels (as dB and
as a bar graph), Sensitivity Level, Storage location number, and Battery Level. Intensity levels are
shown simultaneously as a numeric dB value and on a sixteen-segmented bar graph (with each
segment representing 3 dB). This Ultraprobe receives ultrasound centered around 40 kHz and is
non-adjustable.
SENSITIVITY/STORAGE ENTRY CONTROL DIAL.
This is the most important control in
the unit. It is used to adjust the sensitivity. When clicked, it changes functions such as store data
or change the storage location number. It is also used to get into the “SET UP” mode (described
later).
HEADPHONES JACK.
This is where you plug in the headphones. Be sure to plug it in firmly
until it clicks.
