The Suspension Tester operates according to the well-known EUSAMA principle. However, the diagnostic options are not restricted to the contents of this specification. In addition to the usual road contact values, the following values are also measured and displayed:
- the contact value difference
- resonance frequency and wheel weight at minimum contact value
- tyre rigidity value
- wheel weight
- axle weight
There is a general final evaluation so that all these values do not have to be interpreted after every test.
The Suspension Tester can be used in combination with a VLT Brake Tester. The two pieces of equipment are monitored by the same computer. A single display cabinet is used for the two pieces of equipment. The axle weight measured by the Suspension Tester is also used for the calculation of the brake efficiencies.
Monitor models with 22″, 27″ and 32″ large TFT-LCD monitors with full colour display for information and results.
The VLT 3673/MK2 is a more advanced development of the VLT 3673/M, still fully based on the EUSAMA principle. The VLT 3673/MK2 has the newly developed phase shift measurement, making the EUSAMA measurement somewhat more flexible for the lower wheel weights of small vehicles. The frequency of the VLT 3673/MK2 is controlled by a frequency inverter.
