Fig. 6.2 Transducer connections for a sixwire configuration
(HBM color and connection coding)
The six-wire connection eliminates the effect of cable
resistance. If you are using several transducers, make
the six-wire connection up to the junction box.
6.1.2 Fourwire circuit
You have two connection options for transducers in a
four-wire configuration:
1. Connection without an extension cable; the sense
leads are bridged at the AED (Fig. 6.3).
2. Connection via a 6-wire extension cable; the sense
leads are bridged in the transducer plug (Fig. 6.4).
