9. a kind of delivery rate gyroscope according to claim 1 and plus meter apparatus install polarity measurement method, feature
It is：In the S3 of the step (four), rate gyroscope (8) the installation whether correct judgment method of polarity is：When boost motor is suitable
When hour hands rotate the output of rate gyroscope (8) be just, and when the output of rate gyroscope (8) is negative when boost motor rotates counterclockwise,
Rate gyroscope (8) installation polarity is correct, otherwise mistake.
