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.

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? – Device in use: smart memo pressure measuring case.

First of all, we do not use the normal hydrophobic filter membranes any more but the new improved EFi 1. This not only protects the device from water but also from dust. The dust filter also protects the membranes. To change the dust filter we screw on the union nut. Here you can check if the dust filter is covered with dust. You can change the dust filter separately and you should do this relatively often, because the more often you change it, the better you protect the hydrophobic membranes which are very sensitive. Then you take the union nut and tighten it hand-hot. If you want to change the whole EFi we proceed exactly the same way as with the dust filter, take it out and you can now remove the rest of the filter unit. Here you also see the two hydrophobic filters again. Then you take a new EFi 1, insert it here and screw the union nut on the device, tighten the whole thing hand-tight. This does not have to be pressed very hard. To check whether the union nut is tight and sufficiently sealed, you turn on the device and carry out a pump test. This way you are able to block the gas path completely, which means that no air is drawn past the union nut. And with that the filter change is completed.

I select the menu option Bump Test in the main menu. First I start with the sensor run-in phase in which the sensors have to be purged in pure air.

In the menu point Bump Test, the device is checked for the following: Free flow of the gas paths in the measuring device, Reactivity of the measuring device to test gas, Intact sensors, alarms (optical, acoustic and vibration) First the zero point can be set. Then press Start. The device displays “Please add test gas”. In the case of the OLLI I apply the 5K gas (5 components gas). Test gas can 5 components 1,65 Ltr 35 bar 2.2 % CH4, 150 ppm CO, 2.5% CO2, 15% O2, 25 ppm H2S, rest N2 Capacity: 58 litres Only when the checkboxes are filled in, the bump test is passed and can be verified. The bump test can now be completed with Enter. Please remove test gas. Now the bump test is completed successfully.

Download the Esders Update Tool.

Connect the Link via USB before starting the Esders Update Tool. Switch on the device. Establish the infrared connection between the measuring device and the Link. And press Start in the Update Tool. After the beep, the Bluetooth connection between the Link and the measuring device has been established. The measuring device switches to data mode. If a new firmware version is available, install it using the Update Tool. During the update process the link (our data module) communicates with the device via Bluetooth. No infrared communication is required. The infrared communication is only needed for the first coupling of the Link to the measuring device. The firmware has been updated. By restarting the device the firmware update is successfully completed.
The SAFE EthanTest is a special measuring device, which was designed and optimised exclusively for the analysis of gas samples (for methane and ethane). It has 2 internal pumps and a protocol printer. An essential point for high-quality analysis is the heated separation column. This ensures stable analysis results independent of the ambient temperature. The SAFE EthanTest (SAFE stands for Safe Analysis for Ethane) and other measuring instruments for ethane analysis contain a chromatographic separation column in which the gas sample is broken down into its components and passed through with a time delay. The small molecular methane is the first to reach the sensor and is displayed. After a certain time delay, ethane follows, if it is natural gas. Ambient air is used as the carrier gas for transporting the sample. A pump forces the sample through the column.

You use a gas-phase chromatograph to analyse ethane. What does a gas chromatograph do? – The SAFE EthanTest and other measuring instruments for ethane analysis contain a chromatographic separation column in which the gas sample is broken down into its components and passed through with a time delay. The small molecular methane is the first to reach the sensor and is displayed. After a certain time delay, ethane follows, if it is natural gas. Ambient air is used as the carrier gas for transporting the sample. A pump forces the sample through the column.

The correct use of probes – Why is it reasonable to use different probes for pipeline inspections? When do I use a carpet probe, bell probe or triangle probe? While in Germany and neighbouring countries in urban areas with paved surfaces mainly carpet probes are used, in unpaved areas, such as meadows and fields, the bell probe is usually preferred. In Asian countries the procedure is quite different, e.g. with the triangle probe. To make clear which disadvantages can occur when using the triangle and bell probe compared to the carpet probe, we have made an experiment. The wind has a great influence on our measuring result. A probe should therefore always be placed exactly on the ground so that the wind cannot mix with the escaping gas and “dilute” the concentration. How strong the wind influences our measurement results – we show in the video with a test, which we carried out at our test track in Haselünne with the explosion-proof multi-range gas measuring device OLLI and the bell probe.
