Portable, measuring tools that can be taken away with the test;                             Perform ISO filtering calculations on the X/Y/Z axes during elevator operation to obtain vibration curves and produce elevator operation quality reports.                                       According to the elevator operation quality report, the operation status of the elevator can be easily obtained, and the installation quality of the elevator can be directly judged.                                                 Refer to the national standard requirements, provide curve parameters exceeding the standard label and alarm (function under development)
