Pressure
This is an important menu item. It is used to specify the pressure range, which indicates the
output value. This pressure range forms the basis for many other settings such as the limits for
the relays (warnings) and factors for the flow display.
There are two default settings for the pressure scale:
Top = Pressure at which the output has its maximum value (e.g. 5V, 10V or 20 mA)
Bottom
– Pressure at which the output has its minimum value (e.g. -5V, 0V, 0mA or
4mA)
Because the values can be freely assigned, settings such as 0V at 0Pa or 10V at -250Pa are
also possible.
7.2.1.1 Top
With this menu item, you can set the pressure at which the output will achieve its maximum
value. Any value within the measuring range can be selected. It can also be less than the
lower scale value.
7.2.1.2 Bottom
With this menu item, you can set the pressure at which the output will achieve its minimum
value. Any value within
the P26’s measuring range can be selected.
7.2.1.3 Units
Use this menu item to select the pressure unit. The following pressure units can be selected:
Pa
hPa
kPa
mbar
mmH2O
mmHg
Psi
inH2O
inHg
