5 QuickStart

The Opus Building Vib Module monitors the vibration time signal from a triaxial accelerometer .

When a specified vibration threshold is measured, an event record is  triggered. Then, the event

recordisanalysedtoidentifythepeakforeachaxisandassociatedparameters.

Eacheventrecordcontainsthesimultaneousacceleration,velocityanddispl

acementwaveformsfor

eachaxisandtheacousticwaveforms(TimeSignalandSoundPressureLevels(SPL)).

Step1 ConnectionsandSetup

Connectthemicrophone toinput1andthethreeaccelerometersX,YandZaxistoinputs2,3and4

respectively.

Forpurposesofexample,fastentheaccelerometertoatabl

etop.

Step2 RuntheMeasurement

Clickonthe

buttontostartthemeasurement.Atthispoint,youshouldseetherunning

waveformonthewaveformsgraphsattheleftoftheinterface.

Step3 GenerateEvents

Withtheaccelerometerfastenedtoatabletop,gentlyhitthetabletopwithyoufisttogeneratea

vibrationevent.

Ifthevibra

tionsignalscausedbythevibrationeventwereabovethetriggerlevel,aneventrecording

hasbeentriggered.The

indicatorislightonduringtheeventrecording.

Whenoneeventhasbeenrecorded,itisanalysedtoidentifythepeakinformation.Itisthenadded

anddisplayedontheeventtableandonthespectrum.

Ifanothervibrationeventoccurs,itwilltriggeranothereventrecording.

Step4 StoptheMea

surement

Once the measurement process is completed, click on the

 button to stop the

measurement.
