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 MENU key and select from the list (see below). Frequen-

For RPM-dependent frequency markers (e.g. Imbalance -1st har-
monic), the machine RPM must be known - either by manual entry
or by measurement.
