"1.1.3.2.3 Set URV with Pressure"
Adjustment range:
Within sensor limits
Purpose:
Setting the full scale value
Description:
Use this parameter to set the full scale value to the current pressure value.
The change to the full scale value has no effect on the start of scale value.
This means that the span changes. If the full scale value is less than the
start of scale value, a falling characteristic curve can be achieved. The full
scale value must be within the sensor limits and the span must not fall below
the minimum, otherwise setting of the full scale value will be rejected.
"1.1.4 Trim Mounting Offset"
"1.1.4.1 Perform Trim"
Purpose:
Correction of the zero point error, which is derived from the mounting posi-
tion, among other things.
Description:
The position error and zero point error correction compensates for the errors
caused by the chosen installation position. After the position error correc-
tion, the pressure transmitter shows the pressure measurement value 0.0 in
the respective units.

"1.1.4.2 Correction value"
Purpose:
Displaying the position error correction value
description:
This parameter shows the value of the position error correction that was
performed, in the selected pressure unit.
"1.1.5 Damping"
Conditions:
None
Factory setting:
2 s
Setting range:
0.0 ... 100.0 s, in steps of 0.1 s
Purpose:
Setting the electrical damping
Description:
This parameter sets electrical damping in seconds.
This affects the Primary Variable (PV) "1.1.2 PV Select" (Page 69) and
hence the "4.3 Analog Output" (Page 139) parameter.
