Recently, we created two new instrument drivers to support the JEVAmet VCU series from JEVATEC:
JEVAmet VCU active:

JEVAmet VCU:
https://sweep-me.net/device/341/JEVATEC_JEVAmetVCU
Here, we would like to give you a little guide how to get started. The guide can be also used if you have similar logger-type devices.
-
Download SweepMe! (1.5.7.5 or higher)
https://sweep-me.net/download_sweepme -
To get familiar with the basics of SweepMe!, you can read our Wiki, or watch some YouTube tutorials
-
Now, it is time to download the drivers: Go to menu “Tools” → “Version manager” and search for the drivers, e.g. by typing “JEVAmet” into the Device search bar:
Select a driver in the left list and then activate a driver version in the right box “Versions”. In the above example, the version 2025-06-02 is activated. To do so, click on an online version and use the button “Activate selected version” or download the version via the right-click menu. -
Once the version is installed, we can create a setting in the Sequencer. An exemplary measurement procedure can look like this:
A MakeFile module at the top makes sure that all data is saved to a text file during the measurement. A Loop module is configured to create an endless repetition. A Delay module with a value of 0.1 s makes sure that we do not log more than 10 values per second. For each individual pressure sensor, a Logger module can be added into the branch. -
The Logger module can be found in the tab next to the Sequencer tab:
First, please select the correct driver in the field “Device” and select channel 1, 2, or 3 depending on at which channel the pressure sensor is connected. The next step is finding the port and selecting the correct COM port. In the field “Parameters” you can select the measurement unit and whether communication takes place via RS232 or RS485. In case of RS485 an additional address must be inserted.
That’s all. If you like to read out multiple controllers and pressure sensors, just add multiple Logger modules and configure the COM port, the channel and setup the RS232/RS485 communication to differentiate between them.
Please find the above example as setting file here:
JEVATEC_JEVAmetVCUactive_Example.set (5.5 KB)
After download, you can select it via menu “Settings” → “Load Setting”.
Alternatively, you can copy the following string and paste it into an empty sequencer to reproduce the above branch of modules and their configuration:
