Example 1:
Zero offset
x1in
= 100
x1out
= 100 + 1,5
x2in
= 300
x2out
= 300 + 1,5
The corrected values are shifted evenly with reference to
the input values over the complete range.
Example 2:
Gain change (rotation around the coordinate origin)
x1in
= 0
x1out
= 0
x2in = 300 x2out = 300 + 1,5
The corrected values diverge despite equality with
the input values at
x1in
and
x1out
.
Example 3:
Zero and gain matching
x1in
= 100
x1out
= 100 - 2,0
x2in
= 300
x2out
= 300 + 1,5
The corrected values are already shifted at input
values
x1in
and
x1out
and diverge additionally.
Sensor types
The input sensor type can be defined as potentiometric transducer or as standard current signal.

incl. 2 w RL.
Calibration or scaling are with the sensor connected.

Before calibration, the mains frequency required during operation must be adjusted.

Calibration is as follows.
Transducer calibration is possible via interface and front-panel operation.
Select
set 0%
as shown in Fig.: 26. After pressing the selector key,
set 0%
starts blinking. Bring the transducer
into the position corresponding to X0 (usually lower end position). The instantaneously valid value for INP6 is displayed
‘
X
‘. Press the selector key again to store this actual value as X
0
.
Select set 100% . After pressing the selector key set 100% starts blinking. Now, bring the transducer into the
position corresponding to X
100
(mostly upper end position). The instantaneously valid value for INP6 is displayed ‘

‘.
Press the selector key again to store this actual value as X
