ABSTRACT:
An electronic measuring device capable of indicating a measured value in both analog and digital forms. In this device, the displacement of a spindle is converted into a number of pulses and counted by a counter, and the number of pulses thereby obtained is thereafter indicated by an indicator. On the other hand, a pulse motor disposed in a pointer rotating unit is driven by a driving circuit in accordance with a counted value supplied from the counter so as to rotate a pointer by an angle corresponding to the counted value.
