Level meter adjusts magnetic V-type frame, so that two laser cells is in parallel position and fastens, and opens laser alignment instrument host, into
Enter the measurement interface of software, mobile universal comparator measures main shaft, sets two laser cells greatly in the upper of same upright position
At lower two, it is 0.0mm that the displacement indicating value that two laser cells are shown is arranged in laser alignment instrument host software.
2. the measured value on horizontal metroscope has at this moment been remembered, using this value as radix, then according to certain displacement indicating value school
Requirement (such as interval 1.0mm) on schedule, the corresponding displacement interval value of measurement main axle moving of horizontal metroscope, while reading laser pair
The shift value that two laser cells are measured in middle instrument host, two laser cells are measured in laser alignment instrument host shift value and
The difference of the spacing value of horizontal metroscope measurement main axle moving is exactly the error of indication of the displacement measurement of laser alignment instrument, due to omnipotent survey
Long instrument indicating value is by calibration, so this error of indication value is also that can trace to the source.
The beneficial effects of the present invention are: the present invention is the no relevant national verification rule of calibration in current laser alignment instrument
In the case where journey and calibrating standard, most general metrical instrument need to be only used, several cubings are simply added, using the method energy
Solve the problems, such as that client is traceable to national standard to the angle of laser alignment instrument and displacement indicating value, the method do not need investment it is large-scale or
Special equipment is bought, saves development cost, and solve practical problem for enterprise, also can bring receipts for measurement and calibration unit
Benefit.
