Using the SoundBlaster
®
Some Tru Pointe
®
Ultra HD kits include Bacharach’s ultrasonic sound generator, the SoundBlast-
er ® . The SoundBlaster ® is used to arti fi cially pressurize items and detect potential leaks using a
115dB ultrasonic tone. The Tru Pointe
®
Ultra HD can detect the tone as it escapes in areas that
are not under pressure.
To use the SoundBlaster
®
:
1. Press the On/Off Button once on the SoundBlaster
®
.
2. Place the SoundBlaster
®
inside the item to be tested.
3. Use the Tru Pointe ® Ultra HD to detect the leaked ultrasonic waves generated by
the SoundBlaster ® using the same method as detecting a standard airborne leak.
NOTE:
Using the SoundBlaster
®
inside a symmetrical
object (i.e. a cylindrical tank) can cause standing waves,
which can result in hot and cold spots. For these situa-
tions push the ‘Mode’ button to turn the SoundBlaster
®
’s
burst mode on.
Tips on Use:
1. Sound waves lose strength with distance, so when checking a building for leaks,
do not place the SoundBlaster
® in the basement and attempt to fi nd leaks in the
roof.
2. It is best to remove the nose cone from the SoundBlaster
®
when checking roofs
3. If the SoundBlaster
®
’s tone is too strong, place a piece of sponge or foam in the
nose cone.
4. DO NOT place the nose cone fl at on a hard surface, as the re fl ection of the gener-
ated sound could damage the SoundBlaster
®
