How to exchange modules of a DEWETRON measurement system - featuring picture

There are countless reasons why data acquisition and analysis experts rely on our high-end DAQ systems. One among many others is for instance the distinctive modularity. This means you can adjust any DEWETRON measurement system to make it the right solution for your measurement task. In that way, any DEWETRON system might become a power analyzer simply by adding e.g. the famous TRION3-1810M-POWER-4. Likewise, you can equip your system to measure NVH phenomena with a TRION3-1850-MULTI module. To simply do that, you will find a step-by-step guide on how to exchange modules in the following paragraphs.


The step-by-step guide on how to exchange modules and sub-modules

In the following paragraphs, you will learn how to exchange modules and sub-modules of your DEWETRON system. Thereby, you must consider that proper ESD precautions are a requirement to avoid any damage to the unit. In case of uncertainty, please do not hesitate to contact our support team. If you want to exchange sub-modules of a TRION(3)-POWER module, please follow all the following steps carefully. However, if you want to exchange modules entirely, you can skip steps 4 to 6 as these are sub-module specific.


Step 1

Switch off the instrument and unplug all connected cables including sensors from the TRION(3) series modules.
