ABSTRACT:
A circuit is described here for liquid crystal indication systems made up of segments which, using the capacitive performance of the indication system, automatically reveals errors that arise in the segments or due to short-circuits between segments.
The invention is adapted for use especially in scales that are to be guaranteed against functional errors.
