Page 9: Main Menu
VIBRODIAG 5 Main menu The instrument main menu contains four main items: Measure; Database, routes; VibroGuide and Setup. It is necessary to set/check the Setup item before further instrument use. It is necessary to define the measured places in detail in the Database, routes item, before measuring, and to create/choose a route for these places. -

VIBRODIAG 5.2 Sensor setup Main menu Instrument setup Sensor After preparing the instrument for measuring, it is suitable to enter (or check) the corresponding sensitivities of ICP sensors for both channels (A and B). Sensitivity of each sensor is marked on its upper part and is entered into relevant boxes, see fig. 5. For each channel, it is also possible to select a high pass filter with values 1 Hz, 3 Hz, or 10 Hz. -

Page 14: Measuring
VIBRODIAG 7 Measuring After measuring initiation, the filters will stabilize (ca. 5 s), if the measuring request is initiated immediately after turning on the instrument, then this time can extend to 22 s (the filters are stabilizing during this period). Filter stabilization is always performed in case a different route/place is chosen, with its own setup (range, limits, high pass). -

The balancing result using the test weight does not depend on the wizard setup. It is possible to skip the wizard using Skip wizard and further the balancing continues as follows: First run: By selecting measurements and clicking on the forward arrow starts the rotating wheel vibration analysis in both channels.
