The following functions can be called up directly in the MENU:
Stroboscope
Used to control a strobe light with the frequency at the cursor
position. Move the cursor in the spectrum, to change the flash rate
and adjust to the movement of the illuminated object.
You can use a strobe light to visually slow the movement of an
object, making it easier to analyze, check for proper procedures
and find undesirable vibration sources. By visually ‘freezing’ the
movement, you can, for example, precisely determine the rpm or
the alternating frequency.
To connect the strobe light to the yellow port, use the adapter
available as an accessory (VIB 5.333).
RPM edit
To enter the machine RPM after a measurement, press the MENU key
and click on 'RPM Edit'. Enter the RPM value in the number editor.
Display RMS
This function calculates the RMS value of the spectrum and shows it
on the graph (see below).
Post-Processing
Each spectrum is initially calculated from the measured signal and
then integrated to convert it to the desired measurement quantity*.
Post-processing is provided as an option for subsequently altering the
measurement quantity in the spectrum and for converting a velocity
spectrum into a displacement spectrum , for example.
The ‘Alarms’ diagnosis function is only available if the spectrum is
displayed in the original measurement quantity.
