D) Determination of the correction factor for a cur-
rent input
Determination of the correction factor for, e.g. the measuring pressure input (menu
AB Absolute pressure ), which should be measured in a range of 20 to 70 bar.
1 st step Parameterize lower alarm limit parameter to 20 bar
(assigned to the technical zero point 0 or 4 mA).
2
nd
step Parameterize upper alarm limit parameter to 70 bar
(assigned to the technical end value 20 mA).
3
rd
step Parameterize the offset correction parameter to 0
4
th
step Apply a pressure signal, and/or test current input with calibrated
measuring device and read the measured variable (display of meas-
ured pressure input in bar)
5
th
step Determine the difference from:
actually supplied measuring signal and displayed measured variable
6
th
step Enter this difference as an offset in the offset correction parameter
7
th
step Check the pressure measurement display
The same procedure applies for all analog inputs.
