Using the Touch Probe
The patented Touch Probe accessory is a device that converts solid-borne sounds into airborne
sound the Tru Pointe
®
Ultra HD can detect. For example, the sound of an internal leak in a water
valve will travel to its surface. Touching the surface of the valve with the Touch Probe transfers
the ultrasound into the probe and converts it to airborne ultrasound.
To install the Touch Probe:
1.
Unscrew the nose cone from the Tru Pointe
®
Ultra HD.
2.
Screw the Touch Probe onto the sensor.
3. The
Tru
Pointe
®
Ultra HD is now ready to detect solid-borne sound.
Thermal Expansion Valves (TXV)
The following steps can be used to detect leaks in a TXV using the Touch Probe.
1.
Have a glass of ice water ready.
2.
Remove the TXV capillary tube.
3.
Rest the Touch Probe of the Tru Pointe
®
Ultra HD on the TXV and listen. Hold the
capillary. The TXV should open and the sound of
fl
owing refrigerant should be
heard.
4.
Place the capillary in the ice water. The TXV should close and the refrigerant
fl
ow
diminishing should be heard. If the
fl
ow binds or makes too much noise, there
may be a problem with the system.
