Abstract
A root canal meter is disclosed, wherein measured data are compensated linearly or substantially linearly according to distance between tip of an electrode and apical position and thus compensated data are displayed. According to the invention interrelation between the position of the tip of the measuring electrode and the displayed value becomes clear and also, since the display scarcely varies in the early stage, there is no risk of any sudden change taking place in the vicinity of the apical position, hence the display is easily visible and the meter easy to use.
