Curve recorder
The curve recorder provides a slow trace function, which monitors a signal trend.
A signal selected via a parameter is shown in the form of a curve.
Figure 6-23
The curve recorder-relevant settings are changed by pressing the F5 key or via the
"Commissioning / Service – AOP settings - Curve recorder-relevant settings" menu.
The value of the parameter selected in the curve recorder-relevant settings is output on the
display in addition to the curve and updated every 0.5 ... 24.5 seconds (parameterizable).
With a slowly running time basis (as of 20 minutes/figure), the time basis value flashes in the
header in the 1 s-cycle alternately with the text "slow X".
Assignment of the function keys F1 to F5 is not normally displayed so that the space can be
fully utilized to display the curve. Pressing a function key shows the key assignments. If no
further key is pressed within 5 seconds, the labeling will disappear again.
The curve can be scaled automatically or manually. This is selected with key F3 "scale+" -
F2 "Auto/Manual" followed by confirmation with F5 "OK."
● Auto
The scaling of the curve changes dynamically, it is oriented to the maximum value (for
example, 12.49) and minimum value (for example, 0.00) visible in the display at the
actual point in time. Scaling can be changed step-by-step by pressing buttons F2 and F3.
If measured value noise is shown with an excessively high resolution as a result of the
automatic scaling, then the resolution can be reduced in four steps by pressing button F2.
As a result, the automatic scaling is deactivated. However, if the measured value leaves
the display area, then this is extended. Automatic scaling can be reselected by pressing
button F3.
● Manually
After selecting manual scaling and confirmation with "OK", a window opens in which the
maximum and minimum limits for scaling can be set.
