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.
Nettoyage des ressorts
Des objets peuvent parfois se coincer dans les ressorts et diminuer la puissance d�aspiration. 17. Enlever les ressorts en desserrant la petite vis, puis en les retirant de la �xation. Nettoyer les ressorts à l�aide d�une tige ou d�un objet similaire. Remettre en place les ressorts dans la �xation et resserrer la vis de blocage.
