Voltage output 0 ... 10 V

Factory setting

Measuring range scaled

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

In the set 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�

Current output 4 ... 20 mA

Factory setting

Measuring range scaled

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

In the set measuring range the output signal is between 4 and 20 mA�

Also signalled:

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

• System pressure below the measuring range: output signal 4��3�8 mA�
