VC820 Software

Since I have bought a multimeter VC820 made by Voltcraft, I am quite happy with this device, but I think the software delivered with it is not as good as the multimeter. I could not find any free or open source software, so i have written something by myself.

The software is in an early development stage and can contain a few errors. I am glad about any error that you report to me so that I can fix it.

  • Sending and receiving of measurements by UDP to / from other computers

Needed Components

The software is written with Microsoft.Net, so you need the DotNet-Framework installed. You can get it at Microsoft. Anything else needed is included in the program archive.


At first you need to install the DotNet-Framework. Then, uncompress the program archive in a directory and invoke the exe-file. The program creates a configuration file automatically. If you want, you can create a shortcut to the program on your desktop or in the start menu. That's all.


Code for Java

A developer who does not want to be named has sent me his basic implementation of the data access to the VC820 for java. This is his implementation:
