Especially with chemical seal systems, the installation position of the

instrument can shift (offset) the measured value. Position correction

compensates this offset. In the process, the actual measured value

is taken over automatically. With relative pressure measuring cells a

manual offset can also be carried out.

If the actual measured value should be taken over as correction value

during automatic position correction, this value must not be influ-

enced by product coverage or static pressure.
With the manual position correction, the offset value can be deter-

mined by the user. Select for this purpose the function "Edit" and

enter the requested value.
Save your settings with [OK] and move with [ESC] and [->] to the

next menu item.
