3.2 wIRING DIAGRAMS
Refer to Tables 3-1 through 3-11 to locate the appropriate wire function and wiring diagram. There is a separate table for
each model. The sensor models having the highest number appear first. If you do not know the model number of the
sensor, refer to the flow charts on pages 32 through 34. Only the model option numbers needed to select the cor-
rect wiring diagram are shown. Other numbers are not shown. For all other sensors, see sensor manual.

* Sensors have a BNC connector that the Model 5081-P pH/ORP transmitter does not accept. Cut off the BNC and terminate
the coaxial cable as shown in Figure 3-23. Alternatively, use a BNC adapter.
