displayed with the new unit.
Options:
• mbar, bar
• mmH2O, mH2O, inH2O, ftH2O
• Pa, hPa, kPa, MPa
• psi
• mmHg, inHg
• Torr
• g/cm

Factory setting:
Depends on the sensor nominal measuring range mbar or bar or as per order
specifications
CUSTOMER UNIT P (075)
Entry
Enter text (unit) for customer-specific pressure unit.
You can enter a maximum of eight alphanumeric characters here.

CUST.UNIT FACT.P.
Prerequisite:
• PRESS. ENG. UNIT = User unit
!
Note!
Only the first five characters are shown on the onsite display. For example, if "crates" is
specified as the customer-specific unit, "crate" is displayed.
If the unit contains a slash, up to eight characters can be shown on the onsite display. The
maximum number of characters in the counter is again limited to five. For example, if
"crates/m2" is specified as the customer-specific unit, "crate/m2" is displayed. In
FieldCare, all eight characters are displayed.
In the HART handheld terminal, the customer-specific unit is only displayed in the
CUSTOMER UNIT P parameter. The measured value is displayed with the additional text
"User Unit".
Factory setting:

CUST.UNIT FACT.P (317)
Entry
Enter conversion factor for a customer-specific pressure unit.
The conversion factor must be entered in relation to the SI unit "Pa".

CUSTOMER UNIT P.
Prerequisite:
• PRESS. ENG. UNIT = User unit
Example:
– You want the measured value to be displayed in "PU" (PU: packing unit).
– MEASURED VALUE =10,000 Pa
i
1 PU
– Entry CUSTOMER UNIT P: PU
– Entry CUST.UNIT FACT.P: 0.0001
– Result: MEASURED VALUE = 1 PU
Factory setting:
1.0
SET LRV (245)
Entry
Set lower range value – without reference pressure.
Enter pressure value for the lower current value (4 mA).
Factory setting:
0.0 or as per order specifications
SET URV (246)
Entry
Set upper range value – without reference pressure.
Enter pressure value for the upper current value (20 mA).
Factory setting:
