Troubleshooting Tips
1. Humming sound: Certain electrical products, such as computer
terminals, emit a high frequency “humming” sound. This sound is
not electrical interference—it represents an actual sound that the
TruTrack is hearing. In almost all cases, this sound is not severe
enough to interfere with leak detection.
2. Hissing noises: A certain amount of hiss is normal for ultrasonic
detectors and you can expect to hear it. However, if it is so loud that
you cannot hear anything else, investigate the true cause of the hiss.
3. The signal in the head set cuts in and out: There are two reasons
this problem may occur: (1) a low battery or (2) a bad headset
connector.
4. Not sure the unit is working? Use this test: Can the unit hear the
blink of your eyes? If it can, this unit is probably working well.
Remember that the leak you are trying to nd may not be turbulent.
See “Calibration” if you further suspect a problem.
