Abstract
PURPOSE:To notify the deviation of the measuring tip from the certified measuring range by providing a detecting means and a warning means. CONSTITUTION:A detecting means for detecting and a warning measn for warning the deviation of the measuring tip from the measuring range are provided. For example, a stopper 5a which defines the limit of movement cooperatively with the inside frame 1a is fixed to the spidle 5 carrying a measuring tip 6. A contact point 7 and a corresponding contact point 8 are fixed to the spindle 5 at a desired position thereon and to an insulating member 11 penetrating through the inside frame 1a respectively. When the spindle 5 is lowered as far as a position where the contact points 7 and 8 come in contact with each other, an electric circuit consisting of the conductive spindle 5, the conductive inside frame 1a, wires 10 and 16, a battery 15 and a signal lamp 14 is closed so that the lamp 14 is lighted up.
