VEM-7R dual-antenna RTK test recorder is a multi-functional vehicle performance test equipment with dual-antenna differential GPS system. It integrates data collection, processing and analysis, and touch display. It has high speed and distance test accuracy, simple operation, and data. It has the advantages of convenient and quick handling, compact structure, and easy to carry. The following tests can be completed in accordance with the requirements of the national standard:

(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 rotation test and serpentine test specified by JTT1178.1-2018;

(4) JTT1178.2-2018 specified steady-state circle, steady-state rotation, serpentine, maximum swing and rear 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).
