ABSTRACT:
An inclinometer providing a digital numerical readout includes a level sensor responsive to orientation and means for driving a liquid crystal display to indicate the inclination of a surface with a high degree of precision. Features include high stability with changes in battery voltage and surrounding temperature, a battery condition monitor, freedom from operational adjustments after the initial calibration, and partial blanking of the display to alert a user that the linear inclination limit has been reached. The direct reading digital readout permits ease of operation and a high degree of accuracy and repeatability. Circuitry is especially adapted for low power consumption.
