6.9.2 Setup menu for Pressure measuring mode
Parameter name Description see page
Measuring mode (005)
Selection
Select the "Pressure" measuring mode. 110
Switch P1/P2 (163)
Display
Indicates whether the "SW/P2High" DIP switch (DIP switch 5) is switched
on.
112
High pressure side (006)
(183)
Selection/Display
Determines, which pressure input corresponds to the high-pressure side.
!
Note!
This setting is only valid if the "SW/P2High" DIP switch is in the OFF
position (see the "Pressure side switch" (163) parameter). Otherwise P2
corresponds to the high-pressure side in any case.
112
Press. eng. unit (125)
Selection
Select the pressure unit.
If a new pressure unit is selected, all pressure-specific parameters are
converted and displayed with the new unit.
111
Corrected press. (172)
Display
Displays the measured pressure after sensor trim and position adjustment. 113
Pos. zero adjust (007)
Selection
Position adjustment – the pressure difference between zero (set point) and
the measured pressure need not be known.
Example:
– Measured value = 2.2 mbar (0.033 psi)
– You correct the measured value via the "Pos. zero adjust" parameter
with the "Confirm" option. This means that you assign the value 0.0 to
the pressure present.
– Measured value (after pos. zero adjust) = 0.0 mbar
– The current value is also corrected.
111
Set LRV (056)
Entry
Set the pressure value for the lower current value (4 mA). 121
Set URV (057)
Entry
Set the pressure value for the upper current value (20 mA). 121
Damping switch (164)
Display
Displays the status of DIP switch 2 ("damping "), which is used to switch
the damping of the output signal on and off.
111
Damping value (017)
Entry/Display
Enter damping time (time constant ). The damping affects the speed at
which the measured value reacts to changes in pressure.
!
Note!
The damping is only active if DIP switch 2 ("damping ") is in the ON
position.
111
Pressure after damping
(111)
Display
Displays the measured pressure after sensor trim, position adjustment and
damping.
