As you get nearer to the source of the leak, the LeD's in the vertical bar will light up. The LeD
bar is a relative measurement only. when the LeD display panel reaches 10 lights, you are at
the maximum reading of the range setting. Reduce the sensitivity by turning the thumb wheel
counterclockwise or select a less sensitive range.
7.
Repeat until you have isolated the leak source. Lowering the sensitivity level will verify
that you have isolated the true source, of the leak and not a reflection of the true source.
generally, ultrasonic sound reflections are not as strong as the true sound source.
UT-300 Ultrasonic Transmitter Operation (Shipped in TMULD-300 product)
The UT-300 transmitter can supply ultrasonic signals for locations where the gas/air leak does
not have sufficient pressure to create an ultrasonic sound. This transmitter will allow the
ultrasonic detection of cracks and openings.
