2 Application
2 Application
S531 is a hand-held ultrasonic leak detector that helps you quickly find
and record leakages in compressed air or any gas systems.
When gases leak through tubes and tanks, an ultrasonic sound is
produced. S531 can detect these sound from several-meter away, and
transform these inaudible signals into a frequency that can be easily
heard by ears.
In unpressurised systems, you can use an ultrasonic tone generator to
generate sound that can be detected by S531.
3 Features
•Finds leaks in the compressed air or gas system easily even from
distance
•High resolution 3.5” color touch screen, easing operations in leak
detection
•Almost unlimited memory for leak records
•Wireless connection with headset
•Built-in camera to take photo of leak locations
•Voice recorder for voice memos
•Laser pointer to pinpoint leak locations
•Records leak information for statistics and repair
•Calculates air loss in l/min, m3/h or cfm and in the local currency
•Integrated noise reduction technology
•Battery capacity for up to 8 hours

status is shown on the left top of the
screen.
For a survey in the “Survey On” status,
you cannot change its unit settings like
flow unit, pressure unit, and cash unit.
To change unit settings, you must create a survey with a new survey ID.
In case you want to use the previous survey ID in the newly created
survey, delete data of the previous survey and then reset the S531. For
detailed steps, see Reusing a survey ID on page 23.
8 3 Stopping a survey
When a survey is completed, stop the survey to trigger the S531 to
store the recorded leak data in this survey into a CSV file.

9 Detecting leaks
9 Detecting leaks
After you create and start a survey, you can use the S531 to detect and
record leaks for the survey.
The following steps describe a recommended procedure of detecting a
leak.
1. After a survey is started, the
home screen is shown as the
left-hand side.
Notes:
•The laser pointer is off by
default.
•You can change the
sensitivity by turning the
sensitivity wheel.
2. To turn on the laser, press the
Laser push button as shown on
the left-hand side.
Note: To avoid laser injury, the
S531 allows you to turn on the
laser only when the home screen
is displayed on the touchscreen.
If you enter other screens, the
laser will be automatically
turned off.
3. Point at a suspected leak with
the laser. The leakage grade and
leak amount are shown on the
touch screen.

9 Detecting leaks
4. Mount the trumpet on the
sensor and locate the rough leak
range.
5. When you are close to the
leak point, mount the focus tube
and focus tip onto the sensor,
and scan with the focus tip until
the e act location is found.
16 S531

10 Recording leaks
10 Recording leaks
Once you detect the e act position of a leak point, you begin to record
the leak data.
ATTENTION!
The calculation of leak losses depends on many
factors including pressure, distance, background
noise and so on To get accurate results, we
recommend you record leaks at a fixed distance of
not more than 1 m and with the trumpet on
You can detect leaks from a distance, but keep in
mind that recording loss estimation is best done at a
close distance
Recommended steps are as follows:
1. Keep the trumpet mounted on.
2. Touch the distance value on the screen
and enter an estimated value for the
distance between the sensor and the leak
point. Not more than 1 meter is highly
recommended.
3. Ensure that the pressure value is
correct. Otherwise, revise it on the
touchscreen.
4. When you find the e act position, click
the Record button on the screen.
As shown on the left, a leak record is
created for the leak point. This record is
assigned with a unique leak tag (for
example, 0001) and has the leak loss
calculated.
5. Point the S531 towards the leak point,
and click the Camera icon on the leak
record screen or press the push button
S531 17

10 Recording leaks
to take a photo of the detected leak point.
Two photos at most for a leak.
6. Click the Next button.
7. On the left-hand screen that appears,
click the Microphone icon or press the
push button on the device to record a
voice memo for the leak point.
Two voice memos are allowed for a leak,
and each can last up to 1 minute.
8. Click the Complete button.
9. In the Confirmation pop-up that
appears, click the OK button to save the
record and e it.
10. Fill out the paper leak tag, and then tie it near the leak point.
Note:
To view leak data in a recorded leak, click the Leaks button on the
home screen. For more information, see Chapter 11 Managing leak
records.

and if needed delete the leak and record again.
To analyze leaks, you can also download all leak data in a survey from
the S531 to a PC.
11 1 Viewing and deleting a leak record
You can view a leak record in the S531, and if you are not satisfied with
the leakage data, you can delete the leak record and record again.
1. On the home screen, click the Leaks
button.
The View Leaks screen appears with the
list of leak records displayed.
2. To review a photo or a voice recording
in a leak record, click the corresponding
icon on the screen.

11 2 Downloading leak records to a PC
The S531 enables you to download the leak records to a PC for further
analysis.
To download leak records to a PC, do the following:
1. Connect the S531 to a PC using the supplied USB cable.
2. On the PC, double click My Computer.
On the PC, the S531 is identified as a USB drive.
Note: When the S531 is connected to a PC for the first time, the
S531 driver will be automatically installed on the PC.
3. Access the S531 USB drive.
4. Enter the \records folder.
This folder contains detected data of all surveys. Each of its sub-
folders corresponds to a survey and is named with the survey ID.
5. Enter a survey folder as needed.
A survey folder stores all leak data that the S531 has recorded for
this survey, and is structured as below.
•<SurveyID>.csv stores leak data recorded in this survey.
Note:The CSV file is generated only after the survey is
stopped.
•The ima es folder contains all photos taken in this survey
(*.JPG format).
•The voices folder contains all voice recordings taken in this
survey (*.WAV format).
The image and voice files are named in the form of <Leak Ta
No>A or <Leak Ta No>B (for example, 00001A.jp and
00001B.wav).
6. Copy the desired survey folders to the local.
