3. 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 Place the SoundBlaster inside the item to be tested 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 find leaks in the roof It is best to remove the nose cone from the SoundBlaster when checking roofs 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 flat on a hard surface as the reflection of the gener ated sound could damage the SoundBlaster Tru Pointe Ultra Instruction 0028 9000 SoundBlaster Applications The SoundBlaster is an excellent tool for weatherizing buildings by detecting leaks in windows doors and roofs To effectively use the SoundBlaster and Tru Pointe Ultra HD to check for building leaks 1 Place the Sound
