A See Table, Step 4.
B See Table, Step 5.
2 Select the "Pressure" measuring mode via the
"Measuring mode" parameter.
Menu path: Setup Measuring mode
3 Select a pressure unit via the "Press eng. unit"
parameter, here "mbar" for example.
Menu path: Setup Press. eng. unit
4 The pressure for the lower-range value (4 mA
value) is present at the device, here 0 mbar for
example.
Select the "Get LRV" parameter.
Menu path: Setup  Extended setup  Current
output  Get LRV.
Confirm the value present by selecting "Confirm".
The pressure value present is assigned to the lower
current value (4 mA).
5 The pressure for the upper-range value (20 mA
value) is present at the device, here 300 mbar (4.5
psi) for example.
Select the "Get URV" parameter.
Menu path: Setup  Extended setup  Current
output  Get URV.
Confirm the value present by selecting "Confirm".
The pressure value present is assigned to the upper
current value (20 mA).
6Result:
The measuring range is configured for 0 to +300
mbar (4.5 psi).
