Abstract:
A measurement tool, comprising:a frame having a first member; a second member being moveable relative to the first member along a first axis and a second axis, the first and second members having first and second cooperating structures engageable to enable the second member to be moved downward along the second axis to a preselected elevation when the second member is moved to a preselected position along the first axis, the movement of the second member along the first axis being constrained when the second member is moved to the preselected elevation; a meter coupled to the second member for measuring a height of a feature relative to a reference elevation, the meter having a contact surface that contacts the feature when the second member is moved to the preselected elevation; and an upwardly facing surface positioned substantially at the preselected elevation to enable the second member to be moved into contact with the upwardly facing surface without contacting the feature at which point the meter may be initially set to the reference elevation.
