Important
Transducer connection in a four wire configuration:
When connecting a transducer in a four wire configuration, the sense leads
must be connected to the corresponding bridge excitation circuit (PIN 2'−2
and Pin 3'−3) by wire bridges, as otherwise a sensor error will be detected.
TEDS functionality is not available when connecting in a four wire
configuration.
