FIELD: measurement technology. SUBSTANCE: device incorporates integrated circuit of time reading and control over light-emitting diodes indicator which is matrix with organization 6 x 10 composed of 60 light-emitting diodes positioned in one straight lines or in two parallel straight lines provided with scale of hour and minute reading. Light-emitting diode indicator proper performs function of second reading scale. For display of present time three light-emitting diodes of light-emitting diode indicator emit simultaneously present hour, present minute and present second which is related to consumption of considerable energy. To save power supply source device has mode of disconnection of light-emitting diode indicator without stoppage of time reading by integrated circuit. EFFECT: proposed technical approach expands assortment of devices of electron time reading for individual and collective usage. |
