This GRUNDIG UV5A Owner Manual is not only an instruction manual but a total functional circuit description of the Multimeter and includes circuit diagram at the end pages. It is very helpful for repairing and calibrating the instrument. It is written in two languages English and German for international support. It was very easy to repair my unit with this document. Regards, Regis Pauly, Electrical Engineer.
The owner's manual was evetything I thought it would be. I was able to print it out using both sides of the paper in quick order, saving me a search online for a used one.
Was happy to find the complete owners manual... It's all in there, just like the original...
