Hiding of measured value
In the case of measured values close to a "hold value", it is possible to display the hold value
instead of the current measured value. In this case the hold value is always displayed in a
certain measured-value range, i.e. this range is then always "hidden". The magnitude of the
range to which this applies (parameter: "span") and the hold value can be individually set for
each component. This function can be used to hide e.g. variations in measured value around
the zero point in order to suppress negative displays or to prevent irritation for connected
controllers in the case of small measured values.
The ranges "hidden" in this manner have an effect on all measured-value displays, i.e.
displayed values, analog outputs, and digital outputs.
CAUTION
Risk of undesirable effects with connected positions
With hiding of measured value:
Within hidden measured-value ranges, the displayed value does not usually correspond to
the actual measured value. As soon as the measured value leaves the hidden range, the
actual measured value is displayed again. This effect also occurs in the opposite direction.
This response must be taken into consideration if external controllers are connected.
Without hiding of measured value:
The measured-value displays consistently followed the measured signals, also at the start
of the measuring range. Thus negative values can also occur. Check what the effect of
hiding of measured values has with connected positions.
•
Therefore, before setting the hiding of measured values, check what effect this will have
with connected positions.

Lines 3 and 4 show the smallest possible and largest possible numerical values; the desired
numerical value can be entered in line 2 as described in section Character input (Page 64).
