Pre-test of the system for the purpose of evaluating the optimal parameters to be used for test performance
In order to conduct vibration testing with several independent control channels, it is necessary to have the corresponding number of VCS and shaker systems. In this case, in the “Control parameters” program one should select the generators to be used for vibration testing, and to conduct a pre-test for each of the control channels.
In addition to that, the “Pre-test” program also allows to detect a number of possible errors as well as to provide recommendations in terms of trouble-shooting. To activate this function, click the “Recommendations” key upon completion of the pre-test procedure. Below you can see a brief list of the most common system errors:
- high noise level
- insulation problems
- cable rupture or defect of the transducer
- wrong value of the transducer’s sensitivity
- insufficient contact
- low signal level
- high signal level
- triboelectric effect
- defect of the power amplifier
- disconnected ICP
- high value of signal’s DC component.
