Trend
The standard procedure for monitoring machine conditions is the
regular recording of characteristic overall values over a longer
period of time. The trend of the machine condition can be traced
back from the resulting trend curve and its probable development in
the future can be predicted.
To obtain a meaningful trend, measurements must be carried out
under always reproducible conditions - i.e. machine operating
conditions, measurement location and sensors must be comparable
or identical.
In 'Route' mode, you can access historical measurement data and
reference data that you can compare to the current measurement
data, if necessary.
Trend in a route
• Open the relevant route.
• Select the measurement task for which at least one measurement
has already been saved.
• Start the measurement.
After the measurement, confirm the prompt to save which
appears. Then* the following message appears (see below):
Append: The current result is added to the saved data set and
extends the trend curve (see below).
Overwrite: The current result overwrites the already saved
measurement data.
• To display the trend curve, highlight the measurement task icon
and press the MENU key.
• Click on 'Display Result'. The progression of the measurement
values can be evaluated in the trend screen (see P. 4-3).
Prerequisite: The 'Show result' option in the Route device setup
must be set to 'History' (P. 2-15).
