Our Tutorials
We develop and produce innovative device technology that is made for daily use! Therefore, it is very important to us that you use it effectively and profitably. We want to support you in your everyday work with our measuring devices in the best possible way. Our menu navigation is simple and uniform, regardless of whether it is a gas detector or a pressure measuring system.
What is a tutorial?
To offer you even more assistance we have recorded videos, so-called tutorials. These are small “operating instructions” in a moving image format – for example in the form of a video or an animated graphic – and are intended to guide you to the solution of a possible problem.
Step by step
We explain our measuring devices or individual menu items in detail. The videos are adapted to our proven operation and our uniform handling, so that you can help yourself quickly and easily. Should there be any questions or uncertainties afterwards, our internal and external sales force for technology, support and advice is of course also available to you by phone at any time.
Support where and when you want it
Watch the videos when and where it is convenient for you, whether before using the devices or in between on the construction site. Our explanations and possible solutions lead directly to the desired goal. In addition, videos are more effective than text, because what you see remains longer in your memory than what you read.
Feel free to contact us and let us find a solution together.
In our tutorial on LTE data transmission, Martin Esders explains very briefly, using the smart memo, how to send your test report as a PDF document by e-mail after a completed test.
How does the pairing and detection of external sensors work?

Preliminary test
We have just come from the preliminary test and are doing the pressure release test now.
The pressure is dropping.
For example: The target pressure is 3200 mbar.
The device registers this as soon as it has been reached.
It gives an acoustic signal and also displays a message on the screen.
The user then closes the tap.
The pressure drops a little more due to the reaction time.
But then the pressure rises again due to the contraction.
At 20 mbar, which is how the device is programmed, the switchover to the main test takes place.
Condition: Target drain reached and pressure increases.
The condition is: drainage is to be achieved and a pressure increase must have taken place.
Query volume
A short time later, the query for the drained volumes appears.
The user has to enter this, but otherwise no other things to consider.
During the entire test he only has to wait for the device to tell him:
Target drainage is reached.
And later he will be notified of the query for the volumes.
We are working with our compact compressor KK60, which is connected to our test head HEINZ.
The pipeline is a PE pipeline – outer diameter 225 SDR 11.
We select the menu item B3 Supply line G 469 in the main menu.
First of all, the pipe specifications are entered into the device. We have an inner diameter of 184 mm and a length of 18 meters.
Up to three different pipe sections can be entered into the device.
We have an MOP of 1 bar. The line is grounded.
The permissible pressure change is now adjustable from 0-50 mbar.
The stabilisation time is three hours and the test time 30 minutes.
With F2 we get to the next point.
Summary: Here we can check the entered data again.
We set the zero point. And then the pressure input is carried out with the KK60.
By beeping, the device signals that the test pressure of 3 bar has been reached. Now we are going into the stabilisation phase of 3 hours. After the three-hour stabilisation phase, we automatically enter the test phase: here the pressure is displayed, the starting pressure, the pressure drop and the remaining time. By scrolling through with F1 we see the display: Pressure drop per hour. By scrolling through again we can see the pressure curve in the test phase. The pressure drop is 8 mbar. You can see a small, falling trend in the curve, but it will pass the test.
The starting pressure was 2939 mbar and the final pressure is 2931 mbar. This gives us a pressure drop of 8 mbar with a permissible pressure drop of 50 mbar.
Thus the test was successfully passed.
