Selecting pressure units
After selecting new pressure units all
information on the pressure are converted
into the new units.
Example: After selecting the units "psi" the
measuring
range
from
0...10
bar
is
converted into 0...145.5 psi.

The pressure units in the table below are available:
If you want the pressure value to be displayed in "%", follow the instructions in the section
"Output Pressure in %" below.
Output Pressure in %
If you want the pressure value to be
displayed in "%", set the operating mode to
"Pressure %". The "Display at 4 mA" (V3H1)
and "Display at 20 mA" (V3H2) parameters
set the lower and upper range-values.
Select "%" in the "Unit after Linearisation"
(V3H3) parameter.
