ABSTRACT:
A slope-measuring device is calibrated in terms of the gear in which a multi-gear apparatus should be engaged for negotiating the slope. For example, in a multi-gear bicycle, the calibration may indicate the gear range and specific gear in a bicycle. In a motor vehicle, the slope measurement may indicate the vehicle gear which should be engaged. In order to prevent oscillation of the indication, a high viscosity fluid is employed in connection with a rotating shaft to substantially reduce the response frequency of the indication.
