ABSTRACT:
A device for measuring distances is provided wherein, after calibration of the device, a cursor mounted on an elongate movable wand is moved to the point whose distance from a datum point is to be determined. A resistor extends along the length of the wand and an electrical contact on the cursor makes point contact with the resistor. The contact and resistor form a potentiometer whose output varies directly with the position of the cursor. A digital voltmeter connected to the output of the potentiometer provides an indication of the distance measured.
