1. A portable device for measuring a deflection of a surface, comprising: an elongate frame having a first end, a second end, and a first datum surface;a first removable reference assembly having a second datum surface, adjacent the first end;a second removable reference assembly having a third datum surface, adjacent the second end;the elongate frame member variably locked along a direction generally perpendicular to the elongate frame member at a calibrated distance from the surface by the first removable reference assembly and the second removable reference assembly;a deflection gauge attached to the elongate frame between the first removable reference assembly and the second removable adjustable reference assembly; andwherein the deflection gauge engages and measures the deflection of the surface relative to the first removable reference assembly and the second removable reference assembly. 2. The device of claim 1, further comprising a handle attached to the elongate frame. 3. The device of claim 1, wherein the first reference assembly includes a first contact support, adjustable relative to the second datum surface and the second reference assembly includes a second contact support, adjustable relative to the third datum surface. 4. The device of claim 3, wherein the deflection gauge is calibrated relative to the first contact support and the second contact support at the calibrated distance. 5. The device of claim 3, wherein the second datum surface and the third datum surface are adjacent the first datum surface. 6. The device of claim 3, wherein the first contact support includes a first insulation means for electronic insulation from the surface and the second contact support includes a second insulation means for electronic insulation from the surface. 7. The device of claim 1, wherein the deflection gauge is one of the group of acoustic, mechanical, and optical. 8. The device of claim 1, further comprising: a first extension having a fourth datum surface, attached to the first end of the elongate frame;a second extension having a fifth datum surface, attached to the second end of the elongate frame; andwherein the first reference assembly is attached to the first extension and the second reference assembly is attached to the second end and wherein the fourth datum surface and the fifth datum surface are adjacent the first datum surface. 9. The device of claim 8, wherein the first extension includes a first coupling means for engaging the elongate frame to orient the first removable reference assembly relative to the deflection gauge and wherein the second extension includes a second coupling means for engaging the elongate frame to orient the second removable reference assembly relative to the deflection gauge. 10. The device of claim 9, further comprising: a third extension having a sixth datum surface, attached to the first extension;a fourth extension having a seventh datum surface, attached to the second extension; andwherein the sixth datum surface is adjacent the fourth datum surface and the seventh datum surface is adjacent the fifth datum surface. 11. The device of claim 1, farther comprising: a first extension having a third reference assembly, removably coupled to the elongate frame;a second extension having a fourth reference assembly, removably coupled to the elongate frame; andwherein the deflection gauge is calibrated relative to the third reference assembly and the fourth reference assembly. 12. A portable device for measuring a deflection of a surface and operable by a single user, comprising: a rigid elongate frame member;a first foot adjustably attached to the elongate frame member;a second foot adjustably attached to the elongate frame member;the elongate frame member adjustably fixed along a direction generally perpendicular to the elongate frame member at a set height from the surface by the first foot and the second foot;a measuring tool attached to the elongate frame member;a probe associated with the elongate frame member; andwherein the measuring tool measures the deflection of the surface by the probe touching the surface. 13. The device of claim 12, further comprising a handle attached to the elongate frame member. 14. The device of claim 12, wherein the elongate frame member further comprises weight reduction cutouts. 15. The device of claim 12, wherein the first foot and the second foot are coplanar. 16. The device of claim 12, wherein the measuring tool is attached between the first foot and the second foot. 17. The device of claim 16, wherein the measuring tool is calibrated relative to the first foot and the second foot at the set height. 18. The device of claim 12, wherein the measuring tool includes a memory for storing a deflection value. 19. A method for measuring a deflection of a surface, utilizing a portable device for measuring the deflection comprising: an elongate frame member having a plurality of weight reduction holes, a first foot adjustably attached to the elongate frame member, a second foot adjustably attached to the elongate frame member, the elongate frame member adjustably fixed at a set distance from the surface by the first foot and the second foot; a measuring tool attached to the elongate frame member between the first foot and the second foot; the method comprising the step of: operating the measuring tool to determine the deflection of the surface. 20. The method of claim 19, further comprising the step of calibrating the measuring tool relative to the first foot and the second foot. 21. The method of claim 20, wherein the step of calibrating the measuring tool further comprises the steps of: placing the first foot and second foot against a reference surface;adjusting the first foot and the second foot so that the elongate frame member is parallel with the reference surface; andmeasuring the set distance to the reference surface using the measuring tool. 22. The method of claim 20, wherein the step of calibrating the measuring tool further comprises the steps of: placing the first foot and second foot against a known flat surface;adjusting the first foot and the second foot, so that the elongate frame member is parallel with the known flat surface;lowering the measuring tool to rest against the known flat surface; andadjusting the measuring tool to read zero as it rests against the known flat surface.
