Live Display
The live display allows you to watch the measurement data almost at the same time as they get
measured from the instrument. A graphical chart shows the values versus time. Use this function for
watching changing vibrations e.g. during startup or coastdown of a machine or during the cycle of a
machine tool. This is particularly useful during commissioning or for special tests and troubleshooting.
Connect your PC to the instrument using the COM Port and null modem cable.
From main screen click
Live Display
.
The checkboxes between the graph and the digital display activate the curve for the different units on
the plot.
The control
Sample Rate
sets the time interval between two values to be uploaded.
The switch
Graph
activates or deactivates the chart. On slow PCs this can be useful when writing to
file.
When a signal is higher then the measurement range, a red “over” indicator will replace the digital
value. You might need to go to Setup and change the measurement range.
Storing Data in Live Mode
If you click
Log Readings to File
all data transferred from the instrument will get stored to file. A
dialogue box allows you to enter the file name. Writing starts after you have entered the file name. If
you switch off writing, the logging process gets paused. If you switch writing on again, it will continue
adding data to the same file. If you quit live mode and come back again and start writing, you will be
prompted for a file name again. If you enter the name of an existing file, new data will get appended.
The format of the logfile is tab separated ASCII text. Many software packages like spreadsheets will
easily import files of this type.
The file format is as follows:
Colon:
Content:
1
Seconds since start of recording (or seconds since 01.01.1904 12:00)
2
Vibration velocity in [mm/s RMS]
3
Bearing condition in [gSE]
4
Analog 1 (or velocity channel 2)
