�WARNINGS AND PRECAUTIONS
• Not for use on explosive gases.
• Use extreme care when using near pressurized air/gas.
• Use extreme care when using near rotation equipment.
• Use extreme care when using near electrical equipment.
• Use only 4 x AA batteries for the ULD-400-R Receiver and only 2 x AAA size batteries
for the ULD-400-T Transmitter, properly installed in the battery compartment, to power
the Product (see Section 5: Maintenance).
• Remove the batteries if the Product is not used for an extended period of time, or if
stored in temperatures above 122 °F (50 °C). If the batteries are not removed, battery
leakage can damage the Product.
• Follow all battery care from the battery manufacturer.

Ultrasonic sound, or ultrasound, is a sound wave with frequencies above 20 kHz, higher
than the upper audible limit of human hearing. Ultrasound can be generated when
turbulence created by air or gas is forced through a small orifice. Leaking air or gas is
generally considered to be viscous flow, and as the flow velocity increases, the frequency
of the ultrasound emitted becomes higher. Vibrating, moving objects or electric discharge
will also create an ultrasonic wave, which is very directional in nature and can be used to
pinpoint the exact location of a leak, vibration or discharge.
The ULD-400-R Receiver detects ultrasounds within 20 kHz to 90 kHz frequency, then
amplifies and converts these ultrasonic sounds to frequencies and levels that the human
ear can hear through headphones and show it on the LCD screen. The 20 kHz to 90 kHz
frequency range is the optimal range for detecting a variety of leakage events in assets such
as HVAC systems and pneumatic lines. A change in the ultrasound produced by an asset may
be indicative that an asset is beginning to fail.

3.3 ULD-400-T Transmitter
The ULD-400-T Transmitter is included with the ULD-420 kit and is optional for the ULD-410 kit.
When a leak is not pressurized sufficiently the Receiver will not be able to detect it. In these
circumstances, the ULD-400-T Transmitter can be used to emit an ultrasonic sound that
the Receiver can read. The Transmitter is programmed with three signal levels for precise
pinpointing of leaks.
