Description
1
Function: linear
The characteristic curve type ‚
linear
‘ is se-
lected.
2
Unit
A variable unit for the input signal is
defined with this parameter.
3
Measuring range start
The start of the measuring range is defined
with this parameter.
4
Measuring range end
The end of the measuring range is defined
with this parameter.
5
Limits
Yes (standard value)
No
The display and analogue signal can be
limited to the set measuring range (start -
end) with this parameter.
6
Zero-point window
0.00 … 25.00 %
This parameter is used to set a range
around zero at which the measured value
is set to zero (see fig.).
7
Damping
0.000 … 30.000 s
The input signal can be dampened with this
parameter.
Zero-point window
In many cases, unsteady readings are not a problem during normal operating
mode, but this is not true for the idle state, i.e. if a display value of zero is ex-
pected.
You can use the parameter
Zero-point window
to define a range around zero
(NPF). All measured values within the zero-point window are displayed as a
zero value on the display. If the measured value leaves this range, the display
value f(x) is initially approached. From a window value NPF
exit
, the measured
value and the reading match again.
