5.4.3 Span end (20 mA)
Open the housing cover (for details refer to Opening the device, installing and dismantling the
graphic display on page 16). The pressure span end (20 mA) is provided either from the process
or from a pressure transducer. The pressure must be stable and extremely accurate (<< 0.15%).
Hold the push button (1) down for at least 5 seconds using a blunt object and then release within
10 seconds. The span end set in this way is stored power failure proof.
5.4.4 Factory reset
Open the housing cover (for details refer to Opening the device, installing and dismantling the
graphic display on page 16). Hold down the push button (1) for at least 30 seconds using a blunt
object and then release it. The pressure transmitter now resets itself and loads the factory
settings (see details on page 23).
