Abstract
A monitoring unit also using a multiplicity of segments having a common electrode and each having an individual electrode is connected to the display units and the multiplexer constituting the display so that its common electrode is energized in sequence with the common electrodes of the display units and each of its individual electrodes forms the last of a series connected set of corresponding electrodes in all display units. All electrode sets are energized when the common electrode of the monitoring unit is energized, so that failure of a monitoring segment to light indicates failure of at least one electrode in the electrode set.
