Tips on Use
1. If you are trying to find a leak in a confined area, use the flex tube
insert located in the nose of the instrument. You can use any length
of tubing (it is a standard 1/4 in.), but remember that the sensitivity
reduces as the tube gets longer.
2. When preparing to test for leaks, pressurize the system as much as
safely possible. Increasing the pressure can double the flow through
a hole or crack, making leak detection easier.
3. If the system permits, spray distilled water on the suspect area.
Before the water runs off, scan the area. Water sprayed on a
pressurized leak can also increase the amount of sound created.
4. When searching for vacuum leaks, remember that the majority of
the sound created by the leak is internal. If the system seals permit,
pressurize the system with dry nitrogen in order to increase the
sound of the leak.
