Parameter table
Sensor Min. = Base measuring range start
Sensor Max. = Base measuring range end
Note!
The base measuring range is to be taken from the nameplate!
Note!
Please note that, when setting the measuring range start and end, the
difference between the two must not be less than 25% of the base
measuring range!
The following parameters can be set using the device keyboard (

Δp measuring range [mbar]
Is used to convert the
current differential
pressure into the 4 - 20
mA output signal used.
0 mbar = 4 mA
Upper range value =
