The first step is the ambient temperature, what is the normal temperature? 25±15°C, if there is a regular measurement temperature of the measured specimen, then the regular temperature shall prevail;
The second step is the condition of the product, which is the normal operation status, and the abnormal operation should be stopped in time to deal with the problem;
The third step, the experimental method, mainly according to the rules in the relevant documents of the test sample, is installed on the high-precision turntable with the theoretical output of zero degree azimuth, and then the turntable is adjusted to make the output value of the inclination sensor zero, and then the viewpoint value displayed on the turntable is cleared to zero, and then within the measurement range of the sensor, at least five measurement points are selected, and the readings of the inclination sensor at the test point are recorded respectively. In all test points, from the small point of view (or negative point of view) to the large point of view (or front point of view) in turn, it is a positive stroke, vice versa reverse stroke, each sensor measures a positive stroke or reverse stroke, and among all test points, the absolute value of the error is the largest as the accuracy.
It needs to be noted that when the product output is irregularly beating, it is electrically closed and changed to a manual test to reduce the disturbance of the outside world, and the device should be carried out in the way of the relevant document rules of the sample, and the device surface and the horizontal plane are horizontal/vertical/other viewpoints for the sensing zero point. The test time is greater than or equal to 12 hours after the completion of zero point temperature drift, the accuracy is greater than or equal to 0.02 °, 12 hours after the completion of zero point temperature drift, you can test the accuracy by yourself, the accuracy is less than 0.02 °, and the zero point temperature drift is completed 12 hours after the development engineer admits the accuracy of the test.
