The system ensures the quality of data processing by such strong error judgment capability.
The wire recording module comprises two implementation modes, wherein one mode is an electronic handbook generated by writing software, and the other mode is that the electronic handbook is directly recorded by using a total station memory and then data processing is carried out through a computer.
