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 service manual when downloaded and printed out was clear and easy to read. The manual is complete with the schematic diagram and technical data. I occasionally require a manual and now having registered with this company I shall order from them in the future.
