STETHOSCOPE (CONTACT) MODULE.
This is the module with the metal rod.
This rod is used 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 directly in the module housing. The module
is shielded to provide protection from stray RF waves that may affect electronic receiving
and measurement. It is equipped with low noise amplification to allow for a clear,
intelligible signal to be received and interpreted. For placement align the four prongs on the
back with the corresponding receptacles in the front of the pistol 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), Frequency, Battery Level, and “Display Mode”.
The Display Mode
and the Battery level indications alternate (Flash)
. Intensity levels are shown
simultaneously as a numeric dB value and on a sixteen-segmented bar graph. The
Frequency is adjustable from 20 kHz to 100 kHz. These represent the range of frequency
selection capable with the Ultraprobe. The most common frequency used for general leak
detection or electrical inspection is 40 kHz. These frequencies may be "tuned in" when
performing inspections with any of the
Ultraprobe’s plug
-in modules. The Display Mode
indicates the operation mode of the instrument. This is indicated on the display panel as
R
for Real
Time
, P for Peak Hold, S for Snap Shot, or RO for Real Time “Offset”,
PO for Peak
Hold “Offset” and SO for Snap Shot “Offset”.
For information about Offset see dB Scale
Select in the Set-Up Mode Section.
