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...

Replacing an oven light bulb
You need a 25 Watt small Edison screw with a temperature rating of T300. Make sure the oven is cool before you replace the bulb. Unplug the oven. Open the oven door and remove the oven shelves. Pull the glass bulb cover towards you and then pull it off. Unscrew the bulb by turning it to the left. Fit a new bulb and then replace the glass bulb cover. Replace the oven shelves. Plug the oven back into the electricity supply. Re-set the time of day.
