VEM-7S single antenna tester
Overview
The VEM-7S single-antenna tester is a multifunctional tester integrating data acquisition, processing and analysis, and touch display. It has the advantages of simple operation, convenient data processing, compact structure, and easy portability. The following tests can be completed as required:
(1) Power performance, economy, braking performance, odometer calibration, steep climbing, traction performance test, etc.;
(2) 7 tests of handling stability specified in GB/T6323-2014;
(3) The steady state circle test, steady-state cornering test and serpentine test specified by JTT1178.1-2018;
(4) JTT1178.2-2018 specified steady-state circle, steady-state cornering, serpentine, maximum swing and rearward amplification factor test;
(5) Ride comfort test (need to connect vibration measurement module);
(6) Damping ratio and natural frequency test (need to connect vibration measurement module);
(7) ABS test (need to connect frequency module and analog module).
Main features:
- U disk storage of raw data
- 7-inch industrial touch screen operation, no computer is required during the test
- The start and end of the test have a voice prompt function
- vehicle speed test, GPS update rate optional 20Hz or 100Hz
- After the test, data processing will be carried out on site in real time
- The test results are automatically printed on site or afterwards (optional micro printer)
- PC software supports importing raw data for analysis and generating test reports
- Automatic condition triggering and ending of the test process, supporting manual operation
