Timewaveform recorder
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
'Special' tab.
• Check the measurement settings in the measurement task manag-
er, especially the settings for the measurement time and scan rate.
• To start the recording, click on the icon shown on the right.
• Then enter the file name under which the result is to be saved.
• Signal recording then begins.
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
measurement data that have already been recorded. If the battery
is low 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
signal over one or multiple shaft rotations.
• Press the MENU key and click on 'Postprocessing / Timesynchro-
nous average'.
• Enter the shaft rotational speed (see also p. 4-7).
* Dep. on the sample rate and memory
capacity; a 2 GB memory card and a
sample rate of 512 Hz can record
approx. 132 hours.
