determine the cause of the problem. Using tape saves you from repeating
the checks.
4.2.2. Automobiles
Windshields and trunk seals can be tested by placing the sound generator
on the inside of the automobile and testing on the outside. Be sure the area
to be tested is dry as the capillary tension in the water may block the pas-
sage of sound.
4.2.3. Other Containers
Freezer boxes and refrigerated truck bodies can be tested for tightness like
any other enclosure. Depending on the size, it may be necessary to move
the US 23 every ten feet inside the trailer to maximize its effectiveness.
4.3. Machines and components
Using the flexible touchprobe (see chapter 8) you can detect bad valves
seats and steam traps. Other applications include the detection of friction,
lack of lubrication and worn bearings, motors and gears.
Being careful not the cross thread, simply unscrew the existing nose piece
and replace with metal probe. Place the tip of the probe on the item being
tested with enough force to hold it in place. Be careful around moving
equipment.
5. Troubleshooting Guide
Humming sound:
Certain electrical products such as computer terminals emit a high fre-
quency „humming“ sound. This is not an electrical field interfering with the
operation of the UL 23, it is an actual sound that the unit is „hearing“. To
confirm this place your finger over the sensor hole, and the sound will dis-
appear. In almost all cases, this sound is not severe enough to interfere
with leak detection.
Hissing noise:
There is a certain amount of hiss which is normal for ultrasonic detectors.
You should expect to hear some hissing, however if it is so loud that you
can not hear anything else, it is a problem which deserves attention.
The signal in the head set cuts in and out:
