Abstract
A null-adjusting tool for aligning a tilt sensor of the electrolytic liquid type to the vertical is provided. A sensor mounting plate with a tilt-sensing element attached thereto is rotated about a pivot pin by the rotation of a coarse and fine adjustment screw. The coarse adjustment screw acts directly on the sensor mounting plate. The fine adjustment screw provides a high degree of position resolution control through a combination of screw thread and lever type mechanical advantage. A digital readout containing a liquid crystal display and self-contained power source is mounted on the null-adjusting tool to provide a visual indication of the angular deviation of the tilt sensor from the vertical during the alignment process.
