INCLINATION ANGLE MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To make it possible to easily correct an inclination meter of an inclination angle measuring device and measure inclinations angle in two or more axis directions. SOLUTION: A scale factor correction value S is obtained by controlling a rotation of a turntable 12 by a control unit 14 to measured inclination angles at two positions 180 degrees apart respectively with a servo type acceleration meter 10 mounted on the turntable 12; obtaining an inclination angleθincluding no bias value B nor case alignment value K by means of operating at the control part 14 a subtraction between the values Ma and Mb measured at the above two positions and dividing the result by 2; operating a subtraction between a half of a subtraction between the values Ma' and Mb' measured by the servo type acceleration meter 10 at the same measuring positions when a reference inclination angleαis given to the turntable 12 from a reference inclination angle setting mechanism part 17 and a half of the subtraction between the above measured values Ma and Mb, and dividing the result by the reference inclination angleα.
