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...

CARE AND MAINTENANCE
Cleaning the filters
1. Rotate the microfilter counter-clockwise (in the direction of the arrow �0�) and extract it (E). 2. Remove the wide-mesh filter (F). 3. Remove the fine-mesh filter (G). 4. Clean all filters under running water, paying attention not to bend the fine-mesh filter. Check that no impurities are left inside the dishwasher! 5. To reassemble: insert the wide-mesh filter into the microfilter so it clicks into place. Insert the fine-mesh filter. The filter must be fitted under both tabs (H). Insert the wide-mesh filter / microfilter unit and turn clockwise (in the direction of the arrow �1�), until the dashed lines on the microfilter and fine-mesh filter are aligned. The filter unit must be correctly assembled to ensure good wash results!
