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.
Was happy to find the complete owners manual... It's all in there, just like the original...

HINTS AND TIPS
Lift, rather than slide saucepans on and off the hob. This will reduce the risk of scratches and metal marks from saucepans with aluminium bases. Metal marks can be easily cleaned off providing they are not allowed to burn on. Follow any guidelines provided by the saucepan manufacturer, particularly those relating to recommended heat settings. Avoid using thin, badly dented or distorted saucepans. Those with uneven bases should not be used. Never leave the hotplates ON when not covered with a saucepan. Ensure that the hob and saucepans are clean and dry before the start of cooking. Follow the cleaning instructions very closely to keep the hob looking like new.

If spillage occurs with sugar solutions, e.g. jams and syrups, it must be wiped from the hob before it sets and becomes hard otherwise damage to the hob will occur.
