Description
1
Function: Table
The characteristic curve type ‚
table
‘ is se-
lected.
2
Unit
A unit for the display value is defined with
this parameter. It must have a length of at
least 5 characters.
3
Number of value pairs
This parameter is used to define the num-
ber of value pairs of a table.
4
Value pairs
An input value is assigned to a display
value for every value pair.
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
Damping
0.000 … 30.000 s
The input signal can be dampened with this
parameter.
The table function can be used to correct the input characteristic curve of the
sensor at any point (support points). The changes impact on the display value
and the output signal.
Each support point is stated by a value pair from the input value (Ex) and output
value (Ax). The index 'x‘ states the number of the value pair. At least three value
pairs always need to be stated. The maximum number (n) is 30.
The first value pair is assigned to the start of the measuring range and the last
value pair to the end of the measuring range. There is a linear interpolation of
the characteristic curve between two values. The following value always needs
to be larger than its predecessor. A smaller value is not allowed. In the case of
a decreasing characteristic curve, the successor always needs to be smaller
than the predecessor.
