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.
The instrument setup also enables to switch on or off the sensor power supply. This is
done by checking/unchecking the box, separately for channel A and channel B. If the box
is empty, power supply is turned off and vice versa.
In case of required setup changes, these changes are confirmed by the symbol.

Limits setup
Main menu
Setup
Limits
Limits are used to advise of detected increased values of vibration velocity on the
diagnosed object. These increased vibrations refer to the current machine state. Limits
are displayed in bar graphs (chapter 7.1) and are distinguished by colour. Range
determines the maximal value of the bar graph, item L1 determines the value, from which
the bar graph will colour yellow, item L2 determines the value, from which the bar graph
will colour red. Changes of limit values for signalization of increased levels of vibration
velocity can be done manually using arrows (up, down). Or it is possible to use table
values for the given machine type (sorted by machine power). Automatic tuning is
available using the icon
, subsequently after selecting machine power and setup
confirmation, signal limits are automatically tuned. Automatic limits are set
simultaneously for channel A and channel B. Using manual limit setup, switching among
channels is performed in the Limits menu, via the right arrow.
