In an electronic digital display control device, a pulse generator is actuated to produce pulses which are fed into a counter to control the setting on the display. A discriminator detects whether the frequency of the pulses exceeds a predetermined frequency limit. If the limit is exceeded, the discriminator connects to the counter a second pulse generator which provides pulses at a freqency higher than the predetermined frequency limit. By so doing, the counter receives a substantially greater number of control pulses per unit of time and sets the digital display very rapidly. |
