WIKA Operating Instructions - Process pressure transmitter IPT-2x
Note:
If the current measured value is automatically accepted, it must not
be falsified by medium 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.
After the position correction is carried out, the actual measured value
is corrected to 0. The corrective value appears with an inverse sign as
offset value in the display.
The position correction can be repeated as often as necessary. How-
ever, if the sum of the corrective values exceeds 20 % of the nominal
measuring range, then no position correction is possible.
IPT-2x always measures pressure independently of the process vari-
able selected in the menu item "
Application ". To output the selected
process variable correctly, an allocation of the output signal to 0 %
and 100 % must be carried out (adjustment).
With the application " Level ", the hydrostatic pressure, e.g. with full
and empty vessel, is entered for adjustment. See following example:

1 Min. level = 0 % corresponds to 0.0 mbar
2 Max. level = 100 % corresponds to 490.5 mbar
If these values are not known, an adjustment with filling levels of e.g.
10 % and 90 % is also possible. By means of these settings, the real
filling height is then calculated.
The actual product level during this adjustment is not important,
because the min./max. adjustment is always carried out without
