Osciloskop spojena s generátorem, a asi po páté minut? se zastaví na zobrazení digitálních dat a menu. N?kdy to padá po displeji. Když p?ístroj vypnout a znovu zapnout Potom se již zobrazí na displeji B?hem skok?, ale digitální data.

Oscilloscope connected to the generator, and after about the fifth minute stops to display digital data and menu. Sometimes it falls across the display. When you turn the unit off and on again Then, the display During jumps, but the digital data no longer appears.
