3.3 ULD-400-TE Transmitter
The ULD-400-TE Transmitter is included with the ULD-420-EUR kit and is optional for the
ULD-410-EUR kit.
When a leak is not pressurized sufficiently the Receiver will not be able to detect it. In these
circumstances, the ULD-400-TE 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.
