1 –Introduction
1.1 General Description
AT550 and AT560 make point determination of dirty and clean water leaks in
water pipe lines the device has two seperate sensors, one is acoustic listening
which helps to find clean water pipe network leaks. The other one is system that
is not required headphone and obliged of connection to test pumps and the leak
can be detected on a LCD screen.
1.2 Aplication
•Pipe Lines Leak
•Wastewater pipeline leaks
•Isolation Leaks
•Gas Leaks (for AT550)

4 –Device Function
Nimrof AT550 and AT560 devices detect dirty water and clean water leaks in
water lines as a point. There are two separate sensors for water leaks, one of which
is an acoustic listening sensor that will only help you find clean water leaks. The
other is the AB sensor, which we call “non-listening”, which you can monitor both
dirty water leaks and clean water leaks without wearing headphones, without
connecting a test pump to the water leak line, via LCD. Natural gas leaks can also be
found with the natural gas sensor, which is only in the AT550 model..
•With metal electrode sensors, it can find both dirty and clean water leaks.
•Detects earth ground water leaks.
•Shows acoustic listening in graphic form.
•Ability to use acoustic listening sensor and metal electrode sensor together.
•Ability to use more than 10 water leaks with a ones charge.
•No need for channel imaging or thermal camera thanks to electrode sensors.

4.1 AB sensor Setup
İmages of A and B sensors in the figüre
Sensor A Sensor B
Sensor A : The sensor cable that will stay in the downstairs apartment or in the area
where the water leak is located is 25 meters.Below is the threaded round metal piece
to be connected to the A sensor This part should be touched to the leaking area.
Sensor B : It is the sensor that should be in the upstairs apartment or next to the
user. It is touched to the suspected places and the values are observed on the
screen.
Note: The ends of the cables are colored and must be connected to the 25-meter red
sensor A. The end of the 3 meter cable is black and must be connected to the B
sensor. The free ends of the cables should be connected to the A and B inputs of the
device in color.

4.2 Listening Sensor Setup
Listening Sensor consists of three parts. Cylinder metal part, Short rod and Sensor
Note : The cylindrical metal piece attached to the end of the sensor is used in both A
sensor and the listening sensor.
4.3 Gas Sensor Installation
The gas sensor consists of one piece. Applicable for At550 model only
Note: The cable used is the same as the listening sensor.

5 –Measurement Menu
5.1 AB Sensor
•Activated from the menu button.
•Connections are made as described in 4.1
•The red electrode A is touched to the leaked area and fixed there (25 meters).
•The black B electrode is touched by the user to the suspected places in the
upstairs apartment.
•The numbers on the LCD are observed, the highest values are noted.
•Then the A electrode is removed from the downstairs apartment to the
upstairs apartment. This time, tap and water expenses are touched and
compared with the values taken from the lower flat.
•The numbers appearing on the LCD screen are observed, the highest value is
the area with the leak.
•The AT550 has a Shortcut button for this feature.
Note:
•This feature can be used for both dirty drain water leaks and clean water
leaks.
•You can also use the listening sensor while taking AB measurements
•The values you get from the wall indicate that there is a leak in the wall.
•Garden water leaks are used in the same way as in the apartment.
5.2 Listening Sensor
•Set the volume to the lowest level
•Turn on the device
•Activate the listening sensor from the menü
•Install the listening sensor as described in 4.2
•Plug in the headset
•Connect the listening sensor to the device
•In the Listening sensor menu, this button is the mute button.

Note: You can also observe numerically and graphically on the LCD screen. but be
sure of the water leakage by ear. Do not trust the values on the screen.
5.2 Gas Leaks
This feature is only valid for the AT550 product.
•Install the sensor as described in 4.3.
•Connect the cable to the sensor and the device.
•Shortcut key on homepage
Note: Wait for the sensor to calibrate itself at each start.
