Foreword
Thank you very much for your recent selection of our water leak detector LD-18. This Operation Manual
pertains to operation and handling of water leak detector LD-18.
This manual mainly describes how to use this detector and how to use its software. Make sure to read this
manual and become fully acquainted with operation and handling of this detector before its use. If there is
any matter that is not clear enough to you regarding operation and handling of this detector, please contact
out office.
You are kindly requested to keep this manual in a place of easy access for permitting reference to it whenever
it is needed. If this manual is lost, please contact our nearest distributor.

Use of this detector
This detector has been designed to identify the point of water leak by detecting the water leaking sound,
which is produced out of a waterworks pipe buried under the ground, from the ground surface.
<Overview of detector>
With each of low frequency zone and high frequency zone of output frequency band set at four stages,
noise reduction water leak detector LD-18 is capable of flexibly dealing with the difference in the water
leak sound caused by the difference in the pipe type and with the noise produced on the field, by selecting
a combination that can be easily identified out of 19 different combinations. Furthermore, it permits visual
judgment of the noise level by level bar display. In addition, with noise eliminating function, it is possible
to eliminate accidental noise such as vehicle passing sound and bowwow. This water leak detector
LD-18 is capable of discriminating water leak sound to a level that is higher than that of conventional
detector.
