Info / Alarms
This function checks if a threshold value was exceeded. If so, one of
the LEDs lights up.
To display the thresholds in the spectrum,...
• Press the F key to activate the lower window pane.
• Select the corresponding check box in the tree view.
Info / Frequency marker
Frequency markers can be used to more easily identify the character-
istic machine and component frequencies in a spectrum. Frequency
markers are defined for each machine hierarchy level* in the OMNI-
TREND software and loaded into VIBXPERT with a route / template.
• Press the F key to activate the lower window pane.
• To display the frequency markers of each single hierarchy level,
press the MENU key and select from the list (see below). Frequen-
cy markers from lower hierarchies are added to higher hierarchies
(meas. loc. -> machine -> machine train).
• Activate the corresponding check box in the tree view.
For RPM-dependent frequency markers (e.g. Imbalance -1st har-
monic), the machine RPM must be known - either by manual entry
or by measurement.
