Time waveform recorder

The time waveform recorder can be used to record time waveforms

over very long* times. In contrast, the maximum recording length for

timewaveformsusingtherecordingfunctionisapprox.640seconds

(ata512Hzscanrate).

The time waveform recorder can be found in 'Multimode' on the 'Ad-

vanced' tab.

The measurement screen only shows the entire measurement time

and when the measurement will be ended. The recording can be

stoppedatanytimeusingtheESCbutton.Youcansavethemea-

surement data that have already been recorded. If the battery runs

out during recording, the device automatically saves the data.

The data can be read into OMNITREND via Multimode import and

then analyzed. Alternatively, they can be read out of the device

using the ‘VIBXPERT utility’ service program and imported into a

separate analysis software.

Evaluation on device

After the data have been recorded, you can choose to display the sig-

nal over one or multiple shaft rotations.

• PresstheMENUkeyandclickon'Postprocessing/Timesynchro-

nous average'.

* Dep. on the sample rate and memory

capacity; a 2 GB memory card and a

sample rate of 512 Hz can record ap-

prox. 132 hours.
