PURPOSE:To read a measured value with high accuracy by operating the movement distance and direction of a wheel through an arithmetic means on the basis of a signal corresponding to the angle of rotation of the wheel, and displaying the results digitally. CONSTITUTION:The grip handle 5 of the load measure 1 is gripped, a power-on key 36a is pressed, and the wheel is rotated along a road to be measured, so that the movement distance of the wheel 3 is displayed digitally on a display part 21b as the length measurement result. In this case, the display value is increased when the wheel 3 is rotated forward or decreased successively when the wheel is rotated in the opposite direction. On the other hand, a keyboard 21a is operated like a normal electronic calculator to calculate the length of an arc and area, and further performs functions characteristic to the load measure 1, i.e. check point operation, radius correcting operation, and speed display operation properly. |
