Characteristic overall values - trending
If more than two measurements are saved in a file, the results for
each overall value are displayed as a trend curve (see p. 3-28f).
Markers on the trend curve indicate each individual measurement.
The measurement values at the cursor position, the date, the rpm if
applicable, and assigned events and comments are specified below
the diagram. Use the F key to display the individual results.
With the aid of the displayed threshold line (see p. 3-25), it is
possible to determine if thresholds have been exceeded. If more
than one overall value appears in the diagram, only the threshold
for the highlighted value is displayed (in the below screen: upper
alarm for RMS value). Press the navigation key up / down to mark
the other overall values and display the respective threshold values.
Zoom
Press the '+' button repeatedly to magnify the area around the
cursor. This process can be undone again with the 'Minus(–)' key.
The bars above a diagram show the displayed range relative to the
entire display range.
Deleting individual measurements
If a spurious measurement has been included in the trend, delete
this as follows:
• Highlight the measurement in the trend with the cursor.
• Press the MENU button.
• Click on 'Delete'.
