Current output

Factory setting

Measuring range scaled

P = system pressure, MEW = final value of the measuring range

The output signal is between 4 and 20 mA� It is also indicated:

• System pressure above the measuring range: output signal > 20 mA �

• System pressure below the measuring range: output signal between 4 and

3�2 mA�

Voltage output

Factory setting

Measuring range scaled

P = system pressure, MEW = final value of the measuring range

The output signal is between 0 and 10 V� It is also indicated:

• System pressure above the measuring range: output signal > 10 V�
