3-31
VIBXPERT II 05.2012
Prewarning if measurement values deviate excessively
In the ‘Route’ mode, VIBXPERT recognizes by how much the current
measurement value differs from the last recorded historical measure-
mentvalue. If this deviation is large, the greenLEDon the device
lights up and the symbol R! appears in the results screen.
For this prewarning to appear, the following requirements must be
met:
- The maximum permissible deviation of the measurement values is
set in the OMNITREND software (here: 20%).
- The‘%deviation’and‘Historicaldata’functionsareactivatedin
the OMNITREND Route Editor.
- The settings and data sets have been loaded into VIBXPERT with
the route.
- Thedisplaymodeforrouteresultsissetto‘Standard’(seealso
Devicesetupforroute,p.2-15).
Example:
If the current result deviates from the
previous result by more than 20%, the
green LED lights up.
