Abstract
A digital display measuring apparatus including a movable contact on the body of the measuring apparatus to engage with an object to be measured, an encoder for converting the displacement of the contact into an electrical output signal, a counting circuit for counting the output signal of the encoder, and a digital display for indicating the counted value from the counting circuit. The digital display further includes a measurement indicator unit for indicating the displacement of the contact and a preset indicator unit for indicating a preset value higher than those indicated in the measurement indicator unit. The preset indicator unit includes a presetting device for supplying a reference value to the preset input of the preset indicator unit. With this apparatus even if the object to be measured has a length exceeding the maximum displacement of the contact, the full length of the object may be measured and indicated.
