Patent ID: 7117111

Claim:
An adjusting method of a tilt meter, wherein the tilt meter has a tilt sensor, the adjusting method of the tilt meter comprising: differentiating a plurality of holding signals of the same direction output from the tilt sensor, respectively, to obtain at least a tilt signal; if the tilt signal is not in a predetermined range, a motor is driven to adjust the tilt sensor to limit the tilt signal in the predetermined range; if the tilt signal is in the predetermined range, the tilt signal in the predetermined range is amplified by a predetermined multiple; if the tilt signal after amplification is not equal to a level voltage, the motor is driven to adjust the tilt sensor to proceed a delicate tuning step to adjust the tilt signal to become equal to the level voltage; and if the tilt signal after amplification is equal to the level voltage, the level adjusting of the tilt meter is finished.
