The ground for needing to illustrate has used three groups of hardware and softwares in the utility model practice process respectively, has specifically included:
Usage scenario one:
Laboratory carries out calibration when angular displacement sensor calibration.Angular displacement sensor is rotated in standard by calibration
On standard set-up, the angle-data of software measurement at this time is read, if the error of angle-data value and normal data value is greater than 0.45 °
[class of accuracy 0.5%, angular displacement sensor range are (- 45 °)-(+45 °)], at this time, it is meant that the angle displacement transducer
Device error is larger, is unable to normal use.
Angular displacement sensor is removed from standard set-up first, is placed on the utility model auxiliary locator, carry out-
45 °, 0 ° ,+45 ° of angle calibration.Specific calibration mode is as follows:
1) when carrying out 0 ° of calibration: the positioning plate 7 of the auxiliary locator is placed on horizontal position, can use level
