A measuring device, such as a planimeter, having an increased measurable range for measuring a figure without increasing a length of the measuring device. The measurable range of a planimeter is based upon the a physical length of the planimeter. In order to increase the measurable range of the planimeter, the planimeter is provided with an operation control switch that functions to set a measurement mode of a computer associated with the planimeter to a suspend mode, temporarily halting a measurement operation, so that the planimeter can be shifted to another position. Thus, the measuring range of the planimeter is increased without increasing the physical length of the planimeter.
