Frequently Asked Questions

Q. I purchasted a Vellerman K8115 component tester kit. After assembly it did not work. I need some service data and a schematic diagram to try and get it to work. Can you send me a schematic and service information?


You can find the schematic in the assembly instructions: https://manuals.velleman.eu/article.php?id=734
