Operation of Unit

Operating the TruTrack Ultrasonic Leak Detector

1. Plug the headphones into the jack located on the right side of the

instrument.

2. Slide the sensitivity adjustment all the way forward toward the

sensor. The instrument is now set at full sensitivity.

3. Press and hold the ON/OFF button to turn on the instrument. The

button requires minimal pressure.

NOTE: You can use your left thumb to hold this button and your left

index finger to adjust the sensitivity level. Always start at full sensitivity.

Gradually reduce the sensitivity to reduce the effect of background noise,

if necessary.

4. Hold the instrument as close to the suspected area as possible.

Check around the fittings and piping using a zigzag motion. Cover

all suspected areas.

5. Watch the LED window. If a leak is detected, an increase displays

in this window. You also hear a rushing sound coming through the

headphones. The sound becomes more intense, and the meter

reading increases as the instrument is placed closer to the leak.

NOTE: If there is noise in the area and the display is at its full sensitiv-

ity, reduce the degree of sensitivity until the lights disappear. The display

reading is only for relative measurements.

Observing two lights instead of ten can mean two things:

(1) Either you are far from a suspected leak or (2) the leak is smaller than

the one that produces ten lights. Use the sound intensity you hear in the

headset and the varying number of lights to guide you toward the leak

point. Reduce the sensitivity as you approach to verify you are on the

right path.
